[It/Harry Potter] Would Pennywise and a Boggart approach their "performances" differently from each other?

An example to explain what I mean:

Bob is a boy who just saw *Jurassic Park* for the first time recently, and now he's afraid that a Velociraptor is going to eat him. He's so terrified, that he sleeps with the light on and asks his parents to check the closet and under the bed for raptors.

Imagine that Bob is unlucky enough to encounter a Boggart, and then, the next day, Pennywise locates him.

I assume that they would both take the form of a *Jurassic Park*-style raptor, but would their "performances" be distinguishable from each other? Would they basically act the same while in dino-form, or does Pennywise have additional dramatic flourishes that a Boggart wouldn't bother with?

A Boggart is not truly alive or intelligent.  It's a non-being, and it's in its nature to take the form of a viewer's worst fear, but it doesn't do so out of malice or aggression.  Therefore, a Boggart would likely take the form of a velociraptor, and would exhibit behaviors typical of a raptor from Jurassic Park (hissing, growling, tapping its claw on the floor, etc), but it wouldn't go out of its way to scare little Bobby.  

Pennywise, on the other hand, is absolutely alive, intelligent, and full of malice.  He would do everything in his power to scare the crap out of Bobby, so as to make him a tastier meal.  Pennywise would transform into a raptor, but there would likely be additional unnerving features to terrify Bobby: oversized claws and teeth, the ability to talk, the ability to do supernatural things such as walk on the ceiling or spit fire, etc.  And, of course, Pennyraptor would have no problem pouncing on Bobby and devouring the flesh off his bones.
