Squnk
A squnk is the combination of a squirrel and a chipmunk. Although at one time there were thousands of these critters natural selection had its way. Now there remains only one. A human can be referred to as a squnk if that human has qualities of above animals.
The squnk is fast yet clumsy, after climbing quickly to the top of a tree the squnk will fall, not climb, back down.
