Slingshot

The Slingshot, also referred to as the Enerbeam Express, is a gimmick that appears in Sonic Boom: Shattered Crystal. It is a device that is used in conjunction with the Enerbeam to transport the player between areas.

Description
In its default state, the Slingshot is a round grey platform with a ramp on the front and four reddish-brown feet. On top of it is a reddish-brown dome with a grey frame and a pair of purple caps.

When the Slingshot is activated in gameplay, it folds out into a V-shaped frame and the playable characters will latch their Enerbeams onto each upright, forming an actual slingshot, with the character as the projectile. The player then has to pull back and release the Enerbeam on the Nintendo 3DS's touchscreen, which the playable characters will mimic in gameplay. The characters are then flung from the Slingshot to another, otherwise inaccessible, area.

In the adventure levels of Sonic Boom: Shattered Crystal, the Slingshots are used to move between the playable foreground and background sections of said levels. The Slingshots also appear on the World Maps where they are used to travel between the six areas in the game.
