In the 1940 Disney film "Pinocchio," the name of the pet goldfish belonging to Geppetto was Cleo. The animated film was based on a book titled "The Adventures of Pinocchio" by Carlo Collodi, which was originally published in 1883.
Cleo is an affectionate feminine character who always appears in her goldfish bowl and shows affection to the kitten named Figaro. When Pinocchio is in his marionette stage, Cleo swims in reverse. She makes a memorable squeaking noise when she jumps from her goldfish bowl and kisses both Figaro and Pinocchio. Cleo also made appearances in the films "Aladdin," "House of Mouse" and "Who Framed Roger Rabbit?"
