Scaldera

Scaldera is a boss featured in Skyward Sword. It inhabits the Earth Temple.

Strategy
The boss will face Link as both run through a fiery passage with a pit of lava. During the pursuit, Scaldera will shoot fireballs at Link, and will also try to suck him up. Link can throw bombs to its mouth to stun it, so he can climb through its body (no longer on flames) and hurt its weak point.

Trivia

 * Its name is a portmanteau of "Scald" and "Caldera"
