It's Pet Day and there are a pretty a lot of contests for your pets. Shamus is going to join the smartest pet competition. He's bringing Cedrik, his smart mouse, along. When he left the mouse in the lab, it was gone. Jim and Jake tricked them that they know where Cedrik is, but they don't. Tracey and Shamus had to get the twenty dollars before lunch time, even though, Jim and Jake doesn't know anything.
