Twilight Bandersnatch

Having split from its ancestor, the twilight bandersnatch has evolved a nocturnal lifestyle and has become an egg snatcher, though they will also take down various invertebrates. They typically form small packs of up to 2-3 individuals, and use this to their advantage by having one member distract the parent, should it become aware of their presence, while the others snatch eggs from the nest and run off with them. They also use their numbers to go after large prey, such as the various centiworms and their relatives. A genetic mutation has rendered their photosynthesis inactive, so they now use their frills and "wings" to attract mates and to signal one another. Their digits have grown larger at the cost of losing one on both their hands and feet. They will use stones to break open eggs should they prove to tough to crack with a bite.

Note
The name Bandersnatch comes from two poems by Lewis Carroll, "The Hunting of the Snark" and the "Jabberwocky".
