Stiltonian

Stiltonians are a race of sapient mollusk-like aliens.

Biology
They are known for their fast movements, quick reflexes and gentle nature, being referred as "definitely not biters".

History
Alien hunter Dandy and his friends once captured a zombified Stiltonian, confusing it with an unrecorded species due to its unusual color and traits (it was slow, and definitely a biter). It bit Meow, making him a zombie, and this caused a chain of victims to be afflicted with the zombie disease, until - surprisingly fast - the entire universe joined the ranks of the undead.
