This is the last time the characters have their Season 1-2 designs. Every episode after this one has a new, improved design matching the TV series. (An exception being the Break episodes, where the characters still have the previous designs, but only for those episodes)
This is the only season finale that Lumpy dies in so far (Debatable, he may have survived the crash at the end of the episode).
This is one of two episodes, where both of Lumpy's antlers are shown to be pointing upwards. The other episode is Concrete Solution.
If Flaky and Lumpy survived or died in the bus crash instead of being killed by the baboon, Cuddles would be the only character whose death wasn't caused by an animal.
In the beginning of the episode, all of the kids except Flaky sing the HTF Theme song when entering the Zoo. The other times the characters sing the theme are Cuddles, Flaky, and Giggles in This Is Your Knife, and most of the cast in Happy Trails Parts 1 and 2. They would all later sing the song again in Take a Hike.
Lumpy would later go camping with the same group (with the addition of Nutty) in Take a Hike.
