Who Bugged The Porcupine?

The Porcupine wakes up infested with fleas! Who did this to him? Is it the Coyote (the fleas belong to him), the Pink Flamingo or the Camel? Meanwhile, Sherlock has a toothache but refuses to go see the dentist, claiming that he's not in pain. Will Hermione finally get him there?
