Harp-Twanging Snarp

Small, long-armed, bipedal mammals capable of playing the harp, from the 1956 children's book If I Ran the Circus by Dr. Seuss.

Enterprising lad Morris McGurk has acquired three for his Circus McGurkus. In his circus's opening parade, they ride on the back of a Flummox and play a custom harp, a Three-Snarper-Harp, while stacked on each other's head.

It's also unclear if Snarps are naturally harp-twanging, or if McGurk's are specially-trained Snarps.
