Crocodilla is a female Nile crocodile. Like all crocodile mothers, she is protective of both her eggs and babies. She protects them from predators like monitor lizards, marabou storks, and honey badgers. She can also pursue any other animals from her nest. After the Kratt brothers defended her babies from these predators using Crocodile Powers (Gharial Powers with crocodile DNA) while she was away, the suits reverted them back to human due to incompatible DNA. By the time she got back, she saw them with her hatchlings, causing her to chase the Kratts until Aviva comes with the Hippo Sub.
