Frederica (previously called Fred) is a female Nile crocodile hatchling (like the rest of her siblings), first appearing in the Season 1 episode "Mom of a Croc". She is one of Crocodilla's children. She made an additional appearance in "Creature Power Challenge", in which she was about to eat Chris and Martin in Monarch Butterfly Power and Tarsier Power Suits, respectively, with Crunchina (called Crunchella in that episode) and Snapifer. Martin originally thought she was a boy and named her Fred, but due to the temperature, she turned out to be a girl and Martin renamed her.
