Pixie got quite a few, being one of the few monsters who could damage Moo. But her biggest had to be in the episode "My Name Is Pixie". She rescues Genki from Scale Jells, but is hurt saving him. He saves her from quicksand as they try to return to the group, all as Pixie learns to overcome her differences with Genki. However, they're cornered with no chance of escape, as the Scale Jells have a Healing Factor. The Captain orders her to destroy Genki to save herself, but she refuses. As the Jells power up beam cannons to kill them, Pixie prepares an attack.
Pixie: I take orders from no one! I only fight for what I believe in! My name is...My name is... My name is PIXIE! *completely obliterates the Jells*
