Bloominator is completely immobile. When the player is near, it throws up spike balls from its bloom, two at a time, in an attempt to damage the player. The spike balls are launched at seemingly random angles. These projectiles can be deflected by any of the three shields available in the game.
A badnik resembling Bloominator appears in Sonic 3D Blast. Like Bloominator, it spews spike balls from its mouth in a 360° radius around it. They are indestructible. Each one usually has a different firing pattern.
