Gnip

Gnips are enemies in the Wii video game Super Paper Mario. They are bouncing enemies that appear in Merlee's Mansion that will carry Mario or Princess Peach out of the mansion if they get caught in their grasp (similar to the Sentinels in Tubba Blubba's Castle). The difference is, Gnips are actually trying to help the heroes by getting them away from the mansion because there is danger there. There is also a larger version of the species titled Gnaws that do essentially do the same thing as Gnips.

Due to their guarddog nature and their immense mouths, Gnips may be related to Chain Chomps.

"This is one of Merlee's pets, a Gnip... They're just getting you out of harms way when they kick you out of the mansion...  They look scary, but they're actually quite nice..."
