Sea Fox (Sonic Boom)

The Sea Fox (シーフォックス) is a vehicle that appears in Sonic Boom: Shattered Crystal. It is a blue and yellow RC submarine used by Miles "Tails" Prower to explore underwater caverns of the game.

Description
The Sea Fox is a sleek, albeit short miniature submarine with a blue and orange color scheme. It features a foreplane with a resilient and aquadynamic glass visor on the front and, two smaller engines on the sides of the back rear, and is driven predominantly by screw propulsion via a propeller on its back that strongly resembles Tails' twin-tails. Its also has a flat nose that gives off a strong light to illuminate the deep sea.

The Sea Fox can only be found in the Adventure Stages of Sonic Boom: Shattered Crystal and can only be used by Tails. The Sea Fox can be accessed from yellow and blue pipes which are filled with water and have a depiction of the Sea Fox. Once accessing these pipes, the player will enter a underwater section of the Adventure Stage where they will control the Sea Fox to explore underwater caverns. The Sea Fox features a sonar that will highlight points of interest on the map and can use missiles to clear obstacles. However, the player can only use it for a limited time before the air supply runs out, though they can increase the time underwater by collecting air tanks.

Trivia
