Here's how I think they decided that Knuckles would be an Echidna:
-Okay, we've got this red spiky guy, but we have no idea what he is. What's another spiky mammal?
-Well, there's the echidna, but-
-Perfect! He'll be Knuckles the Echidna!
- -but sir, Echidnas have long snouts and no teeth, and lay eggs!
-Too late! I've already written in "Echidna" with a Sharpie. I'm NOT filling out this form again.
-Can't you just use some White-Out?
-We don't have any White-Out. The interns kept getting into it, and we had to take it away.
