Crocodiles are reptiles that appeared in numerous episodes like "Treasure Island", "Sticky Tape", and "Dora Saves the Prince". One crocodile appeared in the episodes "The Chocolate Tree" and "Doctor Dora". The crocodiles also appeared in other episodes, such as "School Pet", "Dora Saves the Game", "The Fix-it Machine", "Big Sister Dora", "A Crown for King Juan el Bobo", "Baby Jaguar's Roar", "Dora Saves the Snow Princess", "Swiper's Favorite Things", "Dora's Fantastic Gymnastics Adventure", and "Baby Bongo's Big Music Show".

Although the crocodiles are either silent or capable of speaking, the ones in School Pet talk like Pokémon, Explorer Stars, Teletubbies, Tiddlytubbies, and Yoshis, meaning that they repeatedly say the name ("Crocodile, crocodile, crocodile").
