SMAASH! Puppy
Smash Legend
Huh...To me it doesn't look any creepier than actual restaurant mascots so this is a surprise. I always thought the designs had to heavily rely on atmosphere and framing, which is why you hardly ever see them move. Even the nightmare designs feel like they're trying too hard. It's like, we get it. You have teeth...maybe I'm just desensitized to the whole thing. Though...isn't a sizeable chunk of the fanbase made out of children? I seem to recall that being the case, but maybe not.I think the content matters less than Freddy looking creepy. And yes, I do believe he's still creepy looking out of the context of the game. At the very least, there's the possibility that some kids might be afraid of it, which is a definite no no as Sakurai definitely isn't in the business of scaring kids. On the other hand, I suppose Marx is also kind of a creepy toy looking thing that's in the game, but he's a much more optional encounter than bumping into lots of Freddy brawlers online.
As for the whole Marx thing, he may not be mandatory to see, but he isn't hidden either. If they thought he was too scary, he simply wouldn't be there. Or at least, he wouldn't attack you with his nervous system and his eyes wouldn't bulge out of his head and explode.
