SOLVED. Children's book where animals switch places [s]

[[deleted user]]

I'm trying to remember a book I read as a child. In one of the stories, the two main animals decide to switch places for a day, and the nice one one cleans the snarky one's house, does his laundry and all other nice things, while the snarky goes to the nice one's house and eats all his food and drinks all his drink and then as a joke sends a package back. Then they meet back up and tell each other what they did, and the snarky one tells the nice one each thing he did, the nice one says "yes I would have done that" and "yes, I would have done that" but when the snarky one says he sent the package back, the nice one says "oh I wouldn't have done that, that was your birthday present." or something like that.

Anyone remember that?
