I think Shellder is very cute!,actually in a way I think Grimer is very cute too! I don't think it's weird to think any type of Pokemon is cute,because I think every Pokemon is considered "cute" in their own way,so no I don't think it's weird!,I think they both are a very cute,to sum it up!

I dont exactly think of them as cute, but if I had to choose then shelder

I think Grimer's really cute. :3
