Blobcat is Rainy's imaginary pet that possesses various but unknown supernatural abilities.
Blobcat consists of an oval-like body, with two arrow heads for ears, dots for eyes, a fishing hook-like nose and mouth, with four lines for whiskers, two on each side, one angled up and the other angled down. Its paws consist of four half ovals on the underside of the body. Lastly, Blobcat has a tail that varies widely with each appearance, ranging from a single bubbled line to a possible S shape. Blobcat always appears at an angle somewhere between a front portrait and a side profile.
Blobcat enjoys taking people through space in its free time. It is still undiscovered how both Blobcat and its passenger are able to sustain life in the uninhabitable outer space.
