Scaldera

Pyroclastic Fiend: Scaldera is a boss in SS undefined that inhabits the Earth Temple. It appears to be a large, six legged insect-like creature, hosting a molten body with a single eyeball. To protect its weak inner layer, Scaldera hosts an armor-like outer layer of rock.

Strategy
As Link enters the final room and proceeds to its sloped bridge, he encounters Ghirahim inside, who explains his intentions to Link. As a means to release his anger for losing Zelda, he attempts to crush Link with a large boulder, which then emerges into Scaldera and engages Link in battle.

As the battle begins, Link must run across the sloped bridge as Scaldera gives chase. Scaldera will shoot large fireballs at Link, which he can avoid by moving to the side. He can also restock on Bombs there. Link must throw a Bomb at Scaldera to damage it, which will cause it to roll back down the bridge. As Link approaches it, Scaldera will get up and begin inhaling to unleash a fireball. Link needs to throw or roll another Bomb into its gaping mouth, which will explode inside Scaldera and break away some of its rocky exterior. It will then fall to the the ground and its eye will be exposed, which was originally concealed by the aforementioned exterior. Scaldera will be momentarily stunned at this point, allowing Link the opportunity to strike its eye. Scaldera will shortly get up and ignite itself on fire, preventing Link's attacks as it chases him up the slope again. Link must simply throw another Bomb to force it back down, followed by another Bomb into its gaping mouth, to extinguish the flames and continue his attack on the eye once more. It is also possible to attack while Scaldera is chasing him, provided that it is not currently on fire, but this requires excellent timing. Successfully landing an attack on Scaldera's eye while it moves will stun it the same way that feeding it a Bomb does.

As Scaldera receives more damage, its strategy will gradually change. Its eye will eventually start to move as it tries to avoid Link's attacks. Eventually, Scaldera will change its entire strategy as it climbs to the very end of the bridge and then curls into a boulder as it rolls down at Link. This can be avoided by moving to the side just as Scaldera passes. Scaldera's fireballs will also begin curving toward Link.

After destroying its full armor of rock and inflicting enough damage to its eye, Scaldera will be defeated.

Etymology
Scaldera's name is a portmanteau of "scald," to burn, and "caldera," a volcanic crater.
