Oluolu debuted in Pulling Out the Pokémon Base Pepper!. Professor Kukui saw Ash's excitement after watching one of Oluolu's Pokémon Base games on television. As a result, he and Principal Oak arranged a Pokémon Base match for the students of the Pokémon School and their Pokémon, with the three adults commentating the match. When Team Rocket arrived, with Jessie wanting Oluolu's autograph, he agreed to participate in a game between the students and the evil trio. Just when it seemed like Team Rocket was about to win, Oluolu had his Snorlax perform the Z-MovePulverizing Pancake, allowing the school team to win the match. Despite Team Rocket losing, Oluolu still offered Jessie his autograph as thanks for the good game, but before she could take it, Bewear showed up and carried the trio away.
Snorlax is Oluolu's only known Pokémon. He used it during the Pokémon Base match between the Pokémon School team and Team Rocket. It appeared again in Night of a Thousand Poses!, where it was seen on the TV at Professor Kukui's house. It appeared once more in SM129 where Oluolu used it in the preliminary round of the Manalo Conference. It ended up getting knocked out off-screen, eliminating its Trainer from the tournament.
