Diving Corsola

Use the A Button and the Control Pad to make Corsola paddle and dive while also avoiding contact with the fully-charged Qwilfish and Tentacool. Corsola floats upward when not paddling and dives faster when the paddling gains momentum. Going past bubbles gives Corsola a fresh air supply – when you’re all out of love, you’re so lost without him.
