A Stiltonian according to QT's book

Stiltonians are a race of aliens in Space Dandy. They are known for their fast movements and quick reflexes. They are a gentle race, and are definitely not biters.

In the episode Sometimes You Can't Live with Dying, Baby, Dandy and his friends captured a zombified Stiltonian, unaware of its curse and confused by its color and traits. It bit Meow, making him a zombie, and this caused a chain of victims in the zombie disease.
