The Pokémon School class is sculpting with clay today! But while our heroes muse about various Pokémon and places, they disappear one by one—first appearing at the scenes of their musings, then reappearing back at school! They soon realize Nebby had used Teleport to take them to the places and Pokémon they were thinking about.
Meanwhile, Team Rocket is determined to catch Nebby. They succeed, but thanks to Teleport, Bewear carries the trio off…and Nebby makes its way back to Ash—all by itself! After Ash and Pikachu visit the places the rest of the class saw earlier, one thing becomes obvious: Nebby is growing up!
