Fusion Feeder

The Fusion Feeder is a Hardmode enemy which spawns in the Desert Astral Infection biome. It is the Astral variant of Sand Shark, although unlike Sand Sharks it is unable to swim freely through blocks nor lunge at the player through them. Instead, it crawls along the tops of blocks or submerges shallowly, about 1 block deep, to approach the player. It is able to swim and lunge at the player if it is within a body of water.
