What’s wrong with Spike the Pufferfish? That big round head of his kind of makes him look like one to begin with, and the writers get a chance to make a cute visual pun by having Spike literally covered in spikes.

Spike is an easy “butt monkey” character. Need some humor to break up a scene? Add a pratfall to Spike. It’s hard to have this happen to any of the Mane 6 for slapstick humor without appearing mean, but Spike’s role is part straight man to be able to take that.
It can be used effectively (eg Spike’s role in PPOV, as it was very subtle), but here for the film as well as EQG it is very forced.
