Kukku Cruiser

# In the navy, you can sail the seven seas! #

The Kukku Cruiser is the boss of Lake Rocky, faced by Tails in the Sea Fox submarine during Tails Adventures. After the fox has been to Cavern Island and picked up the Anti-Air Missile, further sections of Lake Rocky become accessible. Heading further out in the open ocean, Tails takes on a Battle Kukku anti-submarine vessel. The bird-brained sailors lob depth charge after depth charge into the waters, as the Sea Fox responds with a barrage of missiles into the ship's underside.

Defeating the boss allows Tails access to Green Island.
