Trivia

 * In reality, Alligators aren’t native to Africa, while crocodiles, specifically the Nile Crocodile, are.
 * It’s unknown why the alligator chases the Little Einsteins. The reasons could be either it’s hunting them, though crocodilians in real life don’t attack people on medium-sized or large boats, or it was chasing them out of its territory.
