Savage Sea

Savage Sea is a court in Mario Tennis Aces. It is set on an airship flying over a sea, apparently themed after New Super Mario Bros. U. More airships (most notably those of the Koopalings) can be seen in the background, and Bowser symbols are also seen. The spectators are Bob-ombs, Goombas, Koopa Troopas, Light Blue Shy Guys, Spinies, Hammer Bros. and Sledge Bros.

In-game description

 * "A boat gliding upon the untamed waters of the sea. Hit the mast in the middle to welcome some of that untamed fury on board!"

Adventure Mode
In Adventure Mode, Savage Sea is the fifth area visited. Mario and Toad come here searching for the fourth Power Stone. To do so, they board the Coastal Ferry, which is owned by the brother of the Koopa Troopa who owns the Bay Ferry. After setting sail, a storm brews, and a Blooper challenges Mario to a tennis match. Later, the ship is attacked by Gooper Blooper. After Mario defeats him, however, the Lucien-controlled Wario and Waluigi arrive and reveal that they have already found Savage Sea's Power Stone. Optionally, Mario can accept a challenge from Kamek where he needs to rally the ball until he gets 400 points. Completing it rewards Mario with the Shell Racket.
