dude thanks zach i love pennywise
Dude they show no resemblance.
Popee looks more like a human. He has no whitefaced mask on him, and he has a striped bunny costume on.
Pennywise is completly different in appearance. He has a whiteskinned bald head with tufts of red hair on the side of his head, and has more of a traditional clown outfit. Not even his drastic change in design in the remake shows any resemblance to popee.
