Nutty is the first Happy Tree Friend to die in the television series.
This is one of the few times Cuddles appears with a large group of cast without Toothy.
This is the only season premiere so far where Lumpy dies.
When Giggles, Petunia, Lifty, Shifty, Cuddles, and Handy are entering the roller coaster, Mime's corpse is still nailed to one of the boards if one looks to the board just above them.
For comedic effect, when Lumpy is chasing after Lifty and Shifty, the vehicles they are riding in swap places briefly. Lumpy is in the roller coaster cart, and Lifty and Shifty are riding on the pushcart.
This is Petunia's first onscreen death since Hello Dolly.
When Lifty is shredded by the turnstile, The Cursed Idol and Cub's ball (from Havin' A Ball) fly out. The idol may have been the cause of both Lifty and Shifty's deaths.
Sniffles mouth is not seen throughout the episode until he dies.
This is one of the few episodes where Lifty and Shifty do not steal anything or do anything antagonistic.
This episode is the first to show Sniffles with a shorter snout as opposed to the longer snout seen in the earlier internet seasons.
When Giggles and Petunia are about to fall to their death, Giggles screams the same way she does in Eyes Cold Lemonade, where she is voiced by Dana Belben.
When Cuddles and Flaky see the roller coaster, you can hear Cuddles say "Come on!"
Lumpy is responsible for every death in this episode, although Sniffles is indirectly responsible for Mime's death.
This is one of the only two episodes of the TV series that star Sniffles without him inventing anything, the other one being Idol Curiosity.
This episode marks the second time Handy has laughed at someone's misfortune shortly before his own death, the first being Wheelin' and Dealin'.
Interestingly, Handy's laugh is similar to that of the other episode.
This is the first episode in the series where Russell survives.
Not counting the starring and featuring roles in the beginning, Cuddles is the first character to appear in the TV series, as he is the first one to appear on camera, riding the roller coaster in the background. If one does count the starring and featuring role pop-ups in the beginning, then Lumpy is the first character to appear in the TV series. If one counts the intro of the TV series, because of the page flip, Pop and Cub are the first to appear in the TV series.
This is the first episode where the characters have curved buckteeth.
The music during the Lumpy, Lifty, and Shifty chase scene is also used in the Splitting Hares video.
It is also used as one of the 'panic' music tracks (when the alarm bell is getting closer to ring) in the False Alarm video game.
Disco Bear, Russell, and Flaky are the only survivors of this episode.
Coincidentally, they are the same characters who have objects thrown at them in Chew Said a Mouthful.
This is the first and only time Disco Bear has ever survived a featuring role.
The YouTube thumbnail for Part 2 spoils Cuddles' injury/death.
When Handy is sliced in half, one can only see his humerus, which seems to be fully intact with no remanence of a radius or ulna bone, revealing that his arms are amputated exactly at the elbow and not at the wrist like some have thought.
This is one of the many episodes to have no trees in the background.
The title of this episode is an idiom which means the bad side of town.
A roller coaster ride going horribly wrong and killing everyone involved may be a reference to "Final Destination 3". Furthermore, Mime dies a similar death to the character Erin from "Final Destination 3".
Nutty's death is similar to NOS-4-A2's death in the Buzz Lightyear of Star Command episode "Revenge of the Monsters".
Nutty's death is similar to Bishop's death in the 1986 film Aliens, both of them involve the chest.
One of the stuffed Lumpy dolls later appears in a polluted lake in the future TV episode Every Litter Bit Hurts.
When this episode aired along with From Hero to Eternity and And the Kitchen Sink on YouTube, the alternate title for the conglomeration of the segments was "One Foot in the Grave". Cuddles, Giggles, Flaky, Lifty, and Shifty appear in all three of these episodes. Cuddles, Giggles (Debatable), Lifty, and Shifty die in all three, while Flaky dies twice.
