Act 1 introduces the Purple Frenzy. When activated, Sonic transforms into a large, purple monster that can devour enemies and objects, growing in size and destroying obstacles. The larger you get, the more you can destroy. To find Red Star Rings, you'll often need to use the Frenzy to break through large barriers or devour specific sections of the environment. One Red Star Ring might be behind a large, destructible wall. Another could be in a hidden area revealed by devouring a series of smaller objects. Practice controlling the Frenzy's movement and timing its activation to maximize its destructive potential.
