Recs? A kid's chapter book with two or more authors

[redheadbaker]

DS (age 9.5, going into 4th grade) is doing a summer reading challenge (a Bingo board that the school librarian sent home, kids who complete a row get a prize when they go back to school). One of the boxes is read a book by two or more authors. It's easy enough to find adult books in that category, but not so much for kids. 

Any recommendations? He likes Captain Underpants, Diary of a Wimpy Kid, Origami Yoda, Percy Jackson, and Roald Dahl books (he's read The Witches and Matilda).

James Patterson often co-authors stories and writes stories for kids.  I've not read any of them, but you may find something there:

Oh, perfect! We read Dog Diaries a while back, I didn't realize there were more!

I would also suggest Upside-Down Magic, which has 3 authors.
