||This angry little guy erupts constantly. Watch out for lava burns!
— Patch Plaza
Calderon is a volcano-like enemy from Kirby's Epic Yarn and Kirby's Extra Epic Yarn. It can be found floating in lava lakes and constantly spews fire above its head. Occasionally, it will 'erupt' and spew two molten rocks high into the air, which can be captured using the Yarn Whip. Touching the top of Calderon's head or the molten rocks will hurt Kirby or Fluff.
Calderon is immune to the Yarn Whip and to the Weight move, but it can be defeated by tossing a yarn ball at it.
