, and its expansion Sonic Mania , the Roller mk.IIs appear exclusively in Sonic Mania Plus Mirage Saloon Zone Act 1 ( Knuckles' version only) and 2. Like the original Rollers, they will, in gameplay, curl into a ball and attempt to attack the player. Unlike the original Roller, hitting a Roller mk.II in ball form by either jumping or rolling will not hurt the player. Instead, the Roller mk.II will bounce off the player and uncurl.
Spin Attack while it is not in a ball will be enough to defeat this Badnik. Upon their destruction, they release an Animal.
