Pokémon Tales: Ian
In Vs. Bulbasaur, Conway spots Slowpoke, and captures it with ease. While traveling, Slowpoke lets itself out of its Pokéball, believing that it had resisted capture. It accidentally knocked Elise into a river when it came out. It later eats lunch with the other Pokémon.

In Vs. Hitmonchan, Slowpoke comes out of its Pokéball when Conway planned to choose Poliwhirl. Conway uses it to battle Chopper's Pinsir, having no choice. Slowpoke's ignorance to damage allows it to avoid defeat, and Conway manages to make combos to give it victory.
