|“||This angry little guy erupts constantly. Watch out for lava burns!”|
|— Cast Description • Kirby's Epic Yarn|
Calderons are brown volcano-like creatures with black rocks inside of them, an orange mouth, and a black button located at the top. They look perpetually unhappy.
Calderons sit in the lava of Lava Landing—as such, they are typically below Kirby or Prince Fluff. Calderons attack by shooting two flaming rocks into the air when the heroes get close. One rock goes a short distance upwards while the other goes a higher distance upwards. These rocks cannot be wrapped up into yarn balls. Calderons themselves can be wrapped up into yarn balls, however.
Calderon is derived from the word caldera, a volcanic crater. It may also be derived from cauldron.
Its Japanese name ヨーガンス (Yōgansu) is derived from the word for lava, (溶岩/ようがん yougan).
- In pre-release footage, Calderon shot out two Bomber bombs rather than two flaming rocks.
