MysteryBerries in The Mysterious Rainbow of Colors
In The Mysterious Rainbow of Colors, two Pichu are collecting floating Mystery Berries deep in the forest. They discover a mysterious rainbow fog, which originates from a nearby cottage. Inside, they find a Meowth trying to make a rainbow with a concoction in a vat, but the rainbow drifts at the ground. The Pichu add their floating MysteryBerries to the vat, which allows the rainbow to arc through the sky as intended.
In The Mysterious Stockings, a box of Mystery Berries appears in Piplup's dream along with other items from the Daisuki Tales books.
