Mr. Book Deposit Machine

The school librarian might be the best skeleton after Screwsnail, a giant chameleon skull with legs and even a skeletal hand on his tongue! Unfortunately, if any of the kids aren't reading enough, Mr. Book Deposit Machine gets the blame or even risks losing his job, and we learn in one episode that Yumyum alone brings down the entire school's average literacy. That's really sad for the both of them.
