Sonic and Tails using the Submarine Combo in White Park Zone, Act 3.
Tails uses his tails to propeller himself and Sonic through water.
Unlike its counterpart, the Copter Combo, the Submarine Combo has no actual limit, allowing Sonic and Tails to swim through the water until they exit the move by pressing the Tag Action button again, or get out of the water. However, Sonic and Tails can still drown, and the two are vulnerable to damage from Badniks and hazards.
- Using the Submarine Combo Tag Action, or any other Tag Action, while you are Super Sonic will revert Sonic back to normal.
