Pokémon : S21 | E2 – Now You See Them, Now You Don’t!

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 used Teleport to take them to the places and Pokémon they were thinking about. Meanwhile, Team Rocket is determined to catch Nebby. They succeed when, thanks to Nebby's Teleport Ash and Pikachu visit the places the rest of the class saw earlier and finally wind up at Team Rocket's location! Thanks again to Teleport, Team Rocket is sent back to Bewear and Nebby makes its way back to Ash—all by itself! (Source: Wikipedia)
