The Slingshot, also referred to as the Enerbeam Express, is a gimmick that appears in the Sonic Boom series. It is a device that is used in conjunction with the Enerbeam to transport the playable characters between areas.
In its default state, the Slingshot is a round gray platform with a ramp on the front and four reddish-brown feet. On top of it is a reddish-brown dome with a gray frame and a pair of purple caps. When in use, the Slingshot folds out into a V-shaped frame and the users can latch their Enerbeams onto each upright, forming an actual slingshot with the user as the projectile.
In Sonic Boom: Shattered Crystal, the Slingshot folds out when approached, allowing the playable character to latch onto ituprights with their Enerbeams by pressing . The player then has to pull back and release the Enerbeam on the Nintendo 3DS's touchscreen, which the playable characters mimic in gameplay. When released, the characters are then flung to another, otherwise inaccessible, area. Conversely, the player can leave the Slingshot at any time
In the game, the Slingshots appear in both the adventure leves and on the World Maps. In the adventure levels, the Slingshots are used to move between the playable foreground and background sections in said levels. On the World Maps on the other hand, they are used to travel between the unlocked areas in the game.
