Mrs. Butfish asks All-Star and Dimmy to housesit for her and she wants them to watch her seashell collection. Junior then finds out about the job and he tries to ruin it for them. Then Junior gets Occy to chase Polly, his myna bird, and they accidentally change the address number on the houses. The house next door is going to be demolished the next day and the changed addresses make the workers think that the Butfish house is the one that they are to tear down. While all this is happening, Junior steals the seashells and then tells her that All-Star and Dimmy stole the shells. Luckily, Occy had the foresight to hide the shells.
