When Mario arrives in Koopa Village during the events of Paper Mario, he finds that the Koopas are in an uproar over the Fuzzies, small, fuzzy creatures that enjoy harassing Koopas and stealing their shells. Kooper, a blue-shelled Koopa, begs Mario to reclaim his shell from the Fuzzies. After Mario plays a simple mind game where he must guess which tree the shell-holding Fuzzy is in, he can reclaim the shell and give it to Kooper. Kooper joins Mario's party, and they combine forces to drive away the remaining Fuzzies from the village.
