Minus

Thing type 121, Minus, is a green, spherical enemy with drills for hands used in Arid Canyon Zone. It tunnels underground after the player and jumps up once it is underneath them. When tunneling, it is very difficult to jump on these enemies, although a spindash will destroy them. The Minus was first used in SRB2 Christmas as a basic flying enemy.

Checking Flag [1] / Block Enemies on a linedef will not prevent this enemy from crossing it.
