Beautifully illustrated children's book with a mouse and/or a hedgehog sailing in an umbrella from 80s.

My memory is a bit hazy, but I remember the book had more than one story, and there was something about a paint can in one of them. Either a mouse and/or hedgehog who is carrying the umbrella all morning ends up sailing (and maybe having a picnic) in it after everyone tells them its not going to rain so they wont need it.
