Alpha Porpoise
Alpha poirpose are incredibly excitable and "Type A" creatures. Ever eager to engage in extreme activity for seemingly no purpose at all. Left undisturbed alpha poirposes have been observed performing such "rad" stunts as backflipping, surfing, and coordinated acrobatic feats off of various sorts of handles.
Aside from that alpha poirposes deeply enjoy the thrill of the hunt. They hunt for all manner of reasons, aside from food, such as sport, brinkmanship, and for decidely less wholesome reasons. They are quite smart, for animals, capable of understanding and to a limited degree, engaging, with sapient peoples, who alpha poirposes reportedly consider "uncool hosers."
