|This angry little guy erupts constantly. Watch out for lava burns!|

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 can be found only in the Lava Landing stage.
