Animation was decent, but I agree that the story could have been a little more fleshed out.

Where is the moral?

Animation wasn't bad but why would snail want bullies who kick him out of other parties in his party?

There wasn't too much animation here, but it's good nonetheless. However, I'd say that the sound of turning a page really doesn't make too much sense given that the he had the sign right there, he didn't have to look for it in a book or anything of the sort. It's just a little detail, anyway.
