Trivia/Goofs

 * Moral: Be yourself.
 * Nani's junior high friends, Ellen and Lona, are revealed to live in New York and Los Angeles respectively.
 * The saber-toothed squirrel is a reference to Scrat, a character from the Ice Age movies.
 * This is the only episode where Nani is at fault, as opposed to Lilo and/or Stitch.
 * The wildlife preserve is a parody of the one from the 1993 sci-fi film, Jurassic Park.
 * At the end of the episode, Lilo even mentions that the wildlife park reminds her of a movie she once saw, which is referenced by a living T-Rex that Retro reincarnated by unknown means, a nod to said film.
 * The T-Rex was possibly reincarnated from a chicken or some other species of bird, since birds are said to have descended from dinosaurs.
 * Gantu, Reuben and Hämsterviel do not appear in this episode.
 * In "Woops", Retro erroneously appeared with Gantu's other captive experiments, but he was captured by Lilo and Stitch.
