Scarabesque, or Scara (スカラ) in Japan, is a dung beetle-like Badnik that appears in Sonic the Hedgehog 4: Episode II.
Found in Oil Desert Zone, Scarabesques are commonly perched in undesirable locations such as high ledges, and will attack the player(s) by pushing an endless barrage of explosive spheres designed after dung balls in their path. Because of their placement and attack pattern, they are very annoying Badniks to deal with.
||A Dung Beetle type Badnik designed for use in desert areas. It can generate an infnite amount if large boulders that explode while rolling. A troublesome enemy that is always there in undesirable places.
