Festival allows Kirby and his friends to perform a dance that obliterates all enemies on screen and causes them to drop Point Stars. While it cannot turn undefeated bosses and midbosses into Point Stars, however, it can still damage them significantly. Like Crash, Festival is a single-use ability. The Festival ability only appears rarely, as only one enemy, Donpuff, and one boss, Yggy Woods, grant it. During the dance, all enemies on screen freeze in place.
The hat Festival Kirby wears may be inspired by the dancers in the Rio Carnival, a celebration in Brazil.
This ability was possibly inspired by the scrapped Tonosama ability from Kirby Super Star. Both are based off of dancing/festivals and use flashy objects (Festival using feathers and Tonosama using fans) while using the ability.
