The Wrong Side of the Tracks/Trivia

Trivia

 * Nutty is the first Happy Tree Friend to die in the television series.
 * 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.
 * Lumpy_Lifty_Shifty_swapped_vehicles.png 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.
 * Sniffles mouth is not seen throughout the episode until he dies.
 * This is the first TV episode that Dana Belben had her voice sampled in. The second episode is Snow Place to Go.
 * This is one of the few episodes where Lifty and Shifty do not steal anything or do anything antagonistic.
 * Cuddles' injury is similar to Flippy's injury from the Ka-Pow! episode Operation: Tiger Bomb. However, Flippy was able to survive whereas Cuddles was not. His death is similar to one of Sniffles' deaths in his smoochie.
 * 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.
 * The way Lumpy tries to stop Giggles & Petunia's cart is similar to the runaway subway train scene from "Spider-Man 2".
 * When Cuddles and Flaky see the roller coaster, you can hear Cuddles say "Come on!"
 * After Handy goes through the shards, a white line can be seen going through the middle of his body. This is most likely the glass that cut his body in half.
 * All the characters in this episode, with the addition of Flippy, The Mole, Toothy, and Cro-Marmot, appear in Double Whammy Part I and/or its continuation, Autopsy Turvy (Double Whammy Part II).
 * 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 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.
 * 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.

Cultural References

 * 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 Bishop's death in the 1986 film Aliens, both of them involve the chest.
 * Some fans of both Grand Theft Auto: San Andreas and Happy Tree Friends say that this episode is a reference to a Mission in San Andreas', "Wrong Side of the Tracks", due to most characters in the episode dying and the Vagos gang members dying on the train after getting shot by Big Smoke.

Superlatives

 * 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.

Production Notes

 * 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.
 * This was Francis Carr's first time voicing Russell, and Kenn's first credited time voicing Lifty and Shifty.

Continuity

 * One of the stuffed Lumpy dolls later appears in a polluted lake in the future TV episode Every Litter Bit Hurts.
