After Sonic and the gang lost Captain Whisker and his band of pirates at Haunted Ship, Blaze suggested that they searched the surrounding sea for clues. One of these area was Blizzard Peaks, but due to the shallow water and many icebergs, getting there would be too dangerous in a regular ship.

This allows the Aqua Blast to hover just above the sea and avoid any obstacles.

The player has to dodge incoming rocks, mines and sharks in the water by moving the DS stylus from side to side. To use the watercraft's weapons can either tap or hold down with the DS stylus.
