A Treasure Bag belonging to Pikachu appeared in Pokémon Mystery Dungeon: Team Go-Getters Out of the Gate!. It was found by Team Go-Getters and Pichu upon exiting the Sinister Cave. Later, while Team Go-Getters was battling Skarmory who was holding Pikachu and Pichu as prisoners, Pikachu had Pichu drop out a Quick Seed from the Treasure Bag, which Pikachu kicked into Squirtle's mouth. Using the speed boost from the Quick Seed, Squirtle was able to confuse Skarmory, leading to its eventual defeat.
