Unstable Ice Core
These creatures, found in the Aurora Palace appear to be counterparts to the Stable Ice Core. They have a slightly deranged look, and the ice crystals surrounding them lurch and wobble in an inharmonious fashion.
Similar to creepers, they attack by exploding at their enemies. Blocks caught in the explosion are transformed into other blocks. Typically, blocks will turn into glass or stained clay roughly the color of the original block.
