After his mom gets a worm bin, Jeff deals with the gross reality that he has a tub of bugs living in his kitchen, and Clarence obsesses over feeding the worms.

On a school trip to the Aberdale Natural History Museum, Clarence and Sumo check out the displays, goof around with the exhibits and even remove a tooth from the T-Rex display.

Jeff and Sumo expect no one to show at Clarence's birthday party, just like last year. When dozens of kids arrive, the boys struggle to get face time with Clarence, the popular party host.
