Tails uses his tails to propeller himself and Sonic through water.
The Submarine Combo is a Tag Action in which allows Sonic the Hedgehog 4: Episode II Tails to carry Sonic underwater, like a submarine. This move is unlocked in Sylvania Castle Zone, Act 2.
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.
In Multiplayer mode, like
Copter Combo, Tails' movement is controlled by his player.
Using the Submarine Combo Tag Action, or any other Tag Action, while you are Super Sonic will revert Sonic back to normal.
