Cub is how people like to call a baby bear or younglings of large cats (tigers or lions), which explains his name.
In the internet shorts, there are a few episodes where Cub is not with Pop. However, in the TV series, Pop and Cub are always together.
On Cub's "Collect Them All" card, he is said to be lactose intolerant. This might be false, since Cub drank milk with no problem in Bottled Up Inside. The formula could have been soy or another substitute, but given Pop's track record, this is unlikely.
Cub's voice actress was changed when Ellen Conell moved and was unable to voice Giggles, Petunia, and Cub. However, in Clause For Concern, she voiced Cub.
In Season 3, his alliterate sentence is: Cute kids are cuddly and carefree!
Cub and Pop are the only duo characters that aren't always seen together. This is unless one counts games, as in Stay On Target, Lammy appears without Mr. Pickels.
Pop and Cub's Season 3 featuring card is somewhat similar to their TV series starring card.
Also, their Season 2 starring card is somewhat similar to their part in the opening of the TV series.
Cub was originally going to be called Fuzzy.
Besides Mr. Pickels (if he is does exist), Cub is the smallest Happy Tree Friend.
He is one of the only two main characters to have small black eyes, the other being Mr. Pickels. However, Sniffles used to have them under his glasses in earlier episodes.
Cub survives in 12 out of the 52 episodes he appears in. If he survived his debatable deaths he would have survived 16 episodes.
Cub has more pop-ups than all of the other characters, this is because he has two pop-ups in season 1 and three in season 2.
Cub stars in three TV episodes (along with Pop). However, all of his deaths in them are Debatable, so there is a small chance that he could be one of the few characters who survived all of their starring roles in the TV series. The others are Pop, Mime, and Cro-Marmot.
Since Cub and his father are duo characters, Cub stars in every episode Pop does, even though he has very little screen time in A Hole Lotta Love and Clause For Concern. A featuring role would suit him better in these episodes.
Even though Smoochies usually features one character, in Pop and Cub's Christmas Smoochie, Pop is featured along with his son. This marks Pop's second Smoochie and Cub's first one. However, only Cub dies in that Smoochie.
Pop and Cub are the only duo characters (the other duos being Lifty & Shifty and Lammy & Mr. Pickels) who don't have the same number of starring roles.
In the TV series, Cuddles appeared in all of his starring roles.
In the TV series, Cuddles appeared in all of his starring roles. Cuddles dies in two of the three episodes.
In the third internet season, The Mole appeared in both episodes.
So far, A Vicious Cycle. Cubtron Z, and Spare Tire are the only episodes where he survives while Pop dies. Usually it is the other way around.
Kills and Deaths
He has the worst survival rate out of the bear characters.
Not counting Cubtron Z, he has had the least kills. This is because he is only a baby.
If Cubtron Z was counted, he would surpass everyone's kill count by at least a thousand, including Pop's debatable bird kill count in Read 'em and Weepand possibly Petunia's making the world burn in Breaking Wind .
Besides Lammy and Mr. Pickels, who were introduced in Season 3, Cub is the only character who hasn't killed anyone in the TV series.
Despite Pop's long streak of killing Cub, Cub hasn't been killed by Pop in the season 4 yet.
Additionally the fourth season is the only season so far to have Cub survive more episodes than Pop has.
Cub died in every Season 1 internet short he appeared in (Debatable, see It's a Snap). He also dies in every Kringle episode he appears in.
Out of the characters who rarely survive, Cub is one of the few who have been the sole survivor of an episode. The others are Giggles, Disco Bear, and Mime. Shockingly, Cub does this three times.
Cub is one of seven characters not to have the same kind of eyes as the other characters. The other six characters are Lumpy, Nutty, The Mole, Lifty & Shifty (from the TV series onwards), and Mr. Pickels.
Cub's diaper pin usually changes its position when he turns to the other side; much like Lumpy's antlers, Lammy's bow, Nutty's eye and candy, Russell's eyepatch and hook, The Mole's mole, Handy's tools, Sniffles' pocket protector, and Flippy's beret.
Cub is one of the few characters who have never had a real occupation. The others are Lammy and Mr. Pickels.
Panda Mom's baby is similar to Cub, as they are both small and have the same eyes.
Cub is one of the few characters to eat/drink the remains of themselves or another character, the others are Cuddles (thrice), Giggles (four times, one time offscreen), Toothy, Lumpy (twice, one time offscreen), Petunia, Nutty (twice, one time offscreen), Pop (Offscreen), Flaky (twice, one time offscreen),The Mole (Offscreen), Russell (Offscreen), and both sides of Flippy (thrice).
He is one of four characters that has never driven a car, truck, or other motorized vehicle. The others are: Giggles, Mime, and Splendid.
Cub is one of the few characters who have vomited, the others are Pop, Lumpy, Flaky, and Splendid. Giggles and Cuddles have been seen getting nauseous but have never actually barfed.
