Thundersmall is a half-hour episode which airs on January 23, 2012. This is the episode 3 of the movie.
Oso's pessimism has gotten the best of him when he accidentally caused Buffo's Thundersmall device to shrink him, Wolfie, Dotty, Buffo and Whirlybird, and Wolfie and Dotty were sucked into the laundry room. Since Mr. Dos and Paw Pilot never assigned Oso an assignment like that, it's all up to Oso to rescue Wolfie and Dotty as he faces his greatest challenge yet.
- Since Oso was promoted to a full-time special agent and gave up Paw Pilot for the next special agent in-training, it is not a TV show episode. It is a movie episode.
- Since this was the last episode to be produced, it may be implied to be a series finale.
