What are cryptozoologists to make of creatures like this, reported only once? Are they to infer the possible existence of a population of Hopping Devils lurking somewhere out of sight in the fastnesses of New Jersey? Should they speculate on the existence of an interdimensional barrier across which such a creature, well known in its own dimension, might have hopped?
I don't know. The other thing that strikes me is that this creature might have been the far-famed Jersey Devil, not recognized as such by the witnesses.
