Act 1 introduces the Blue Cube. When activated, Sonic transforms into a heavy cube, crushing enemies below and activating blue-colored block switches. This Wisp is particularly useful in underwater sections, as it allows Sonic to sink quickly. To find Red Star Rings, you'll often need to use the Cube to break through destructible floors or activate switches that open new paths. One Red Star Ring might be hidden beneath a blue block that needs to be activated. Another could be in a secret area revealed by crushing a specific section of the floor. Practice using the Cube to clear groups of enemies efficiently.
