While Courtney and Tiny Tina are away at the vet, Dr. Schmeltz, for a check up, Mr. D tricks Mo into doing something. He learns that playing tricks on people is not a good thing to do. Also, Mr. D finds out that telling the truth is much better than making excuses.
Mr. D is fed up with gang and seizes the opportunity to visit his former owners (believing it to be a better home) and starts packing. The others soon realize they don't want Mr. D to leave, and Mr. D comes to realize he is already in the best place he could be, at Courtney's home with his friends.
On a rainy day, Mr. D gets accidentally locked outside in the rain. After trying to get their attention inside the house, Mr. D is finally rescued from the rain. Later, the doors get stuck again, but this time Mr. D is inside dancing to loud music while Courtney and the others try to get his at...
Everyone is settled into an inside activity on this windy day. Oogleberry is painting, Mo is playing with a ball, Mr. D is doing a jigsaw puzzle, Tiny Tina is dancing, and Courtney is reading. But Tina's dancing disrupts everybody else's activities.
