In the episode of the Wild Thornberrys called "The Dragon and the Professor" when Eliza is looking for a Komodo Dragon, at the very beginning, she tells Darwin something like, "Darwin, I have to find that dragon, tomorrow we are leaving for Australia!" Then, later in the episode when they are looking for the dragon again, she says something about "We have to find it tomorrow we are leaving for Spain!" It's not a big deal, but still a slip-up.
