Crabominable is a crustacean Pokémon resembling both a horsehair crab and the mythical yeti. It is mostly white, with a blue face and details, and light yellow hair with two taller hairs sticking out on top. It has fur, and has extra furry spots around its arms, mouth, and claws. Its arms are segmented into three parts, with a blue dot on the middle segment. Its claws have the appearance of a dark blue foot print or paw print, with the biggest mark being the actual claw. It has four legs with blue tips made out of ice, which can freeze a victim when touched. Its face consists of a light blue "mask", closed eyes and a large mouth that goes down into its chest fur. It has two large teeth showing as well. It has a marking on its chest probably to make it appear more like a yeti, which is usually portrayed as ape-like. On its stomach is an armor plate that is blue with light blue stripes.
As a Crabrawler, it evolved and grew fur to bear the cold on snowy mountains. It is capable of smashing thick walls of ice to bits, and turning back avalanches. It often launches flurries of punches without thinking. At desperate times, it can lop off its cold-filled pincers and fire them like rockets.
