Appearing in groups, they float around a room, only moving in 45° diagonal directions, bouncing off solid terrain. They move twice as fast as Pink Giant Diatoms. They look like purple glazed donuts with white sprinkles.
Corrupted Form Edit
When corrupted, Giant Diatoms move slightly slower, but can destroy some solid terrain that is impervious to all of Trace's weapons and upgrades except the Red Coat. Spiru also have this corrupted ability.
