Packaged Rainbow

The Packaged Rainbow is a treasure in Pikmin: The After Years that is held by a monstrous Treetle on the final sublevel of Green Garden. It is a box of crayons. When collected, the Acid Armor is given to leaders, granting them complete resistance to acid such as that produced by acid geysers, Acidic Bulblaxes, and Acidic Blowhogs.
