Yeah, that's who I was thinking of too. Obviously the colors are a bit more subdued with the shark, but it seems to have that same kind of cartoony 3d effect with the animal mugging for the "camera".

edit: here's an example Lisa Frank that the shark feels similar to...the animal just floating in space, mouth open, angled toward the viewer, with other ocean accoutrements just kinda strewn about with wonky perspective.
