Paper Wiggler is a prequel/midquel to Paper Mario: Sticker Star, and it is likely to have a sequel.
Wiggler was a normal Wiggler that lived in the forest until the Shy Guy Troop poisoned all the leaves. He goes on an adventure to save the forest, but he falls asleep. Mario awakened him with a trumpet, and was separated by Kamek. After Mario defeated Gooper Blooper, he ate many leaves, but Wiggler fell asleep again and awoke on a mysterious island.
