Disruptor

The Disruptor is an enemy type and a relatively random element in the game. Unlike most other enemies, the Disruptor does not follow or attempt to attack the player, but rather tries to get away. If the player does not destroy the Disruptor in time, it burrows into the ground and disappears.

Three Disruptors spawn per world, each in a random level. They are not restricted to regular levels, but may spawn in secret ones or a boss level as well. Destroying all Disruptors yields 50,000 bonus points.
