While the characters have been shown to be very incompetent, which is the main cause for a majority of the deaths, the characters are also capable of being very smart and having good ideas that sometimes help a character escape fatal predicaments.
Cuddles isn't the smartest character thanks to his reckless and often rash behavior, he often thinks too fast and doesn't think about the way some of his decisions affect other characters. Even then, he still has his very rare smart moments.
- Who's to Flame?: Cuddles is the only firefighter to notice smoke coming from a distance and warned the other firefighters about the burning house.

Toothy is rather impulsive and usually doesn't think before he does something and sometimes gets himself and other characters into easy to avoid situations. Basically, his mind is like Cuddles', careless and reckless sometimes, but only slightly smarter due to being less of a daredevil.
- Aw Shucks!: He knew jumping in the lake would stop the bees from swarming around him.
- We're Scrooged: He puts together all of the toys that get sold at Lumpy's toy store.
- See You Later Elevator: While it's unknown what Toothy was typing about, he managed to finish typing it. Considering how he works as an office worker, getting a paper typed completely is a huge deal.

Lumpy is often considered to be one of the dumbest characters on the show, as he is responsible for a lot of stupid acts, which leads to the deaths of either himself or everyone around him. While this may be true to a degree, he simultaneously manages to pull of incredibly smart actions throughout the series (More so than any other character in the show) that may question his title as "dumbest character".

Petunia's intelligence is to Giggles what Cuddles' intelligence is to Toothy. She's isn't very bright when it comes to making decisions and her fear of germs sometimes takes away all reason and common sense in her mind, to the point of complete insanity. However, at times when there is time to think, she is capable of doing several wise actions.
- Gems the Breaks: She and Giggles run a lemonade stand that earns a lot more cash than one would expect from a regular lemonade stand.
- A Change of Heart: Calls the hospital on Disco Bear when she realizes he's having a heart attack.
Handy is one of the more intelligent characters on the show. He has his small share of idiotic moments, but he is for the most part a very smart and clever character. The only mistakes he causes are often a result of him forgetting his lack of arms, which he has no control over and therefore killed for his ignorance of this fact.
- Numerous episodes: He is seen driving and piloting numerous vehicles, despite his lack of hands, and he hasn't had a single car accident to date.

- Don't Yank My Chain: Immediately after he and The Mole got arrested, he tried to reach for the keys to unlock their cell door. He gets an idea to brake their chain with a sledgehammer and a spike (though, it would've been better if The Mole was the one holding the spike). Later in the episode, he tells The Mole to get in the water and to leave their ball on the log so when the log goes up the ramp to the saw, the ball will be cut in half, when his plan fails he uses his head to turn off the saw, instead of trying to use his hands to do it. He also tries to break the chain by letting a train run over it (in real life this would've worked).
- Concrete Solution: When he struggles to open his truck's door, he simply exits his truck by squeezing through an open window.
- Who's to Flame?: He douses a burning house with water from his helicopter. Handy is also the only character who actually put out any fires in the episode.
- A Hole Lotta Love: He knows the coordinates to get to the bottom of the well from underground. Though he can't really explain how to get there to Pop with his lack of arms.
- See What Develops: When Mime knocks down Handy's ladder, Handy manages to use his teeth to grab onto the wire of a sign he hung up.
- Home Is Where the Hurt Is: He manages to build a house for Giggles, despite his lack of hands (but as soon as Giggles tries to enter her new house, the house falls apart). He manages to get five or four (debatable, because Lumpy wasn't in the group Handy was giving orders to) volunteers to help with building a new house for Giggles. He manages to open 8 doors, despite his lack of hands, and runs towards the last door to knock it open, using his head. And finally, he spots a nail before he could step on it, so he just jumps over it.

Even after his failed attempt to boil Cub's milk bottle, Cub is seen drinking milk, which means that Handy somehow succeeded after that failed attempt. He also puts Cub in his crib and uses a fan to cool down his swelling face.
Because of his candy addiction, Nutty often doesn't think before he acts. This makes him one of the dumber characters in the show. Despite that, he has shown some signs of intelligence should it usually not relate to sweets.
- Icy You: Even if it was illegal, Nutty took advantage of Lumpy's stupidity in order to take as much candy in the store as he wanted.
- From Hero to Eternity: He is able to beat Sniffles in a game of checkers. This is ironic, since Sniffles is often considered to be the smartest character.
- Take a Hike: While all of the other characters were starving and miserable, Nutty was actually the only character to find a natural resource that would save him from dying of starvation or natural causes, a beehive. Also instead of just tearing into the beehive like one would expect him to, he sticks a straw inside it and slurps the honey, therefore not agitating the bees.
- Chew Said a Mouthful: Nutty knew that throwing items off the hotdog cart would help increase his speed to Toothy.

- Random Acts of Silence: Nutty, along with Sniffles, appear to be aware of how annoyed Flippy was getting over Mime's actions and tried to escape before he actually flipped out.
Sniffles is often regarded as the smartest character on the show, from having intelligence in basic math and science to building a range of complex inventions - even though the vast majority of them end up backfiring on him in deadly ways thanks to his lack of common sense.

Pop isn't the smartest character. He can come off as very stupid at times but his biggest problem comes from the fact he is very ignorant and clumsy. When he's actually paying attention he can make some pretty good and reasonable decisions.
- Chip Off the Ol' Block: Moves Cub away from the lawnmower when he tries to remove a brick from the blade. He then turns the lawnmower off and removes the brick.

- Chip Off the Ol' Block: Uses a lawnmower.
- A Hole Lotta Love: Despite only being a baby, he was able to get ice cream and take care of himself for a whole day.
Flaky is another one of the slightly wiser characters. Her constant fear of everything around her makes her a very cautious character. Despite this she is just as capable of making stupid decisions like everyone else.

- Breaking Wind: Hides behind a fence to avoid being caught by the tornado while everyone else stands in the open.
Because The Mole is blind, he has a somewhat excuse for not being considered a stupid character. The Mole is actually pretty smart because even without sight he seems to know how something he wants to use is suppose to work. (E.g. A camera in See What Develops or his phonograph in No Time Like the Present)
- Mole in the City: Uses one of his mole bombs to blow the knob off a locked door. He also tricks The Rat into stealing a wrong suitcase, which turned out to be full of his mole bombs, which kill The Rat later on.

After realizing that he and Shifty are stuck in their apartment due to their door being frozen shut, Lifty quickly thinks of using a blowtorch to melt the ice holding the doorknob frozen (that would've worked since fire can't freeze in the first place).
- Claw: He and Shifty try to save Cuddles from the claw.
Unlike his brother, Shifty seems to have very low intelligence level. Most of his acts of intelligence are not solo, but he comes up with some smart decisions along with Lifty. But even Shifty can make some smart decisions on his own sometimes.
- Happy Trails Pt. 2: Jumping the Shark: He and Lifty use a raft to help everyone leave the island.
- Milkin' It: Although a very selfish act, he throws his brother off their hot air balloon in order to make the hot air balloon lighter and avoid being electrocuted to death.

Mime can come of as a very ditzy, but he sometimes lacks common sense. Despite this, Mime is capable of making smart decisions and is often the first character to spot danger.
- Mime and Mime Again: Tries to dab some alcohol on Toothy's open wound. Fixes Toothy's leg by snapping it back into place.

- Wingin' It: Shows everyone on the plane how to use the breathing masks. Gets Lumpy to put away his typewriter.
Just like Handy, Cro-Marmot isn't a stupid character. He may in fact be one of the smarter characters in the show as he rarely does anything that's stupid, but at the same time he doesn't do to many things that could be considered smart.
- Numerous episodes: Despite being encased in ice, he is a great driver and just like Handy, he never had a truck accident.
- Dino-Sore Days: Uses his intestine as a lasso in order to get away from a dinosaur.
- Wipe Out!: Even if it might've been cheating, he freezes the ocean, which eliminates the competition and makes it easier for him to win.
Both sides of Flippy are easily smarter than a majority of the other characters, that's not to say they haven't done stupid things to. This may be because of their age and experience in the war.
- Several episodes: Fliqpy doesn't kill handicaps, the injured, or infants as it goes against war code. (Debatable)
- Hide and Seek: Fliqpy sets a pit trap covered with leaves for Petunia to fall in.

- A Vicious Cycle: Fliqpy was able to kill Disco Bear, Pop, and Lumpy with Cub's tricycle in matter of minutes after possessing it.
Splendid is one the dumber characters of the show and perhaps the dumbest character in the show. He often thinks for himself over others and is blind to the mistakes he causes in almost every episode he is in. Splendid has come up with good ideas to save the other characters, but every single one of them backfires, often killing the victim or making the situation worse had Splendid not interfered.
- Helping Helps: After hearing Giggles screaming, Splendid flies off to rescue Giggles from being hit by the flood.
- It's a Snap: He ties Lumpy's severed arm like a balloon knot to stop the blood from spilling out. He also comes up with an idea to get the bear traps off of Lumpy: he karate chops them off.
- Better Off Bread: He flies around the Earth several times to make it spin the other way around, thus going back in time.
- From Hero to Eternity: Gives Cuddles mouth-to-mouth. He actually had the right idea in using his heat vision on the large snowball, but the snowball ends up getting sliced instead of melting. Drills a hole in the ground to get rid of the flood.

- Breaking Wind: Consumes the tornado.
- Just Be Clause: Splendid crushes Petunia's coal ring and turns it into a diamond.
Despite being recently added to the cast, Lammy has already proven to be a very unintelligent character and has yet to do something noticeably or at least undoubtedly smart.
- A Bit of a Pickle: When Flaky stops due to a huge log blocking her way, Lammy immediatly hits the brakes to stop Handy's truck from crashing into Flaky. She also ducks when she stops the truck, as if she didn't duck, those steel sheets that killed Flaky would've most likely killed her too (Debatable, she may have accidentally ducked and survived by sheer luck).
Mr. Pickels is the only, character who hasn't performed an act of stupidity (not counting Cub since he's a baby). This may make him the smartest character in the entire show, that is if he's a living creature and not just a figment of Lammy's imagination.
- A Bit of a Pickle: Starts Handy's truck up with a screwdriver.
- Royal Flush: Sneaks into one of the sandwiches and allows himself to be eaten by Flaky, when he's pooped out he sneaks out of the toilet and kills Flaky (This is also the only time he's killed someone without Lammy).
