Fiesta sets treats around the user's team's field. Fiesta can be set up to three times. Pokémon who switch into the field where there are treats will regain 1/2 of their HP and consume one layer of treats.
The moves Rapid Spin and Engulf will remove treats from their user's side. The move Defog will remove treats from its target's side.
The user scatters delicious candy on its side of the field. This candy heals Pokémon who switch in.
