Protopet

Protopets are Megacorp's genetically modified pet. Designed as the ultimate plaything, the pet was released with defects by Captain Qwark, who was masquerading as Abercrombie Fizzwidget. The released pets began to attack people all over the Bogon Galaxy, causing chaos. They can open their mouths and spawn 3 more, and there can easily be 50 on one screen.

The Mutant
Quark's plan was to have saved Bogon from the pets he unleashed and appear as a hero in the eyes of the citizens. When Ratchet, Clank, and Angela Cross were captured trying to stop him, Qwark chose to frame them for the Protopet's rampage as revenge for his first defeat at Ratchet's hands. However, due to an accident with Angela Cross's Helix-O-Morph, the original pet became a ravenous mutant and had to be neutralized by Ratchet, who returned the pets to a docile state.
