Scaldera

Scaldera is a boss featured in Skyward Sword. It inhabits a Fire Dungeon.

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 a bomb to its mouth to stun it, so he can climb through its body (no longer on flames) and hurt its weak point.
