I mean just think about it: In Japan, Shyguys are called "Hee-ho", referring to the sound they make. "Hee-ho" is also the pseudo-catchphrase of Jack Frost in the Shin Megami Tensei series, or SMT for short. Spell it backwards and you get TMS, the acronym for Tokyo Movie Shinsha, an animation company that has worked on a large amount of western cartoons such as Ducktales. This is clear evidence that Dhyguy is secretly a duck, possibly even a McDuck.
