Spider Kirby is one of Kirby's copy abilities. It was introduced in Kirby Star Allies. It is typically obtained from Como. Kirby wears a purple bowler hat with six golden plates in this form with appendage-like feelers coming down each side.
The core of Spider Kirby's moveset is spinning webs that can trap foes while they last. Trapped foes can be easily dispatched and their bodies can knock over other enemies.
In Star Allies, Spider Kirby can create a web platform to bounce allies on. This is called Friend Bounce.
