Molten Shard

The molten shard is a giant lava rock that falls out of Death Mountain thanks to Fyrus. To some people when they had to run around in circles trying to avoid the falling rocks and then seeing a giant shadow following them, they probably peed their pants. Luckily enough, it never hits you. The shard is also used to melt all the ice away in Zora's Domain. After the Molten Shard has freed the Zoras, and the Lanayru Province has been freed from twilight, the Shard can be blown open with a water bomb to reveal a trapped Goron, who apparently fell into the lava in Death Mountain and was blown violently out of the volcano while inside the rock. Oncefreed, the Goron will give you a bomb bag.
