When Biscuit gets peas stuck in her fur, Dodge mishears and thinks she has fleas. The misunderstanding sends the rest of the pups into a frenzy, thinking that fleas are spreading around the school.

Everyone's excited about the scavenger hunt, until they discover Miss Collie has mixed up the pups' usual groups. Dodge misses his best friends and has to learn to work with Tiny.

It's show and tell day, and it's Bertie's turn to share with the class why he loves gardening. The pups are keen to give it a go but haven't fully listened to how it should be done.
