When activated, Sheik throws a small grenade connected to a chain, presumably the same one seen in Melee and Brawl. The throwing animation involves Sheik throwing with her left hand, spinning around on one foot, then landing on one knee before standing back up. After being thrown, the grenade will activate a vortex effect, pulling any close by opponents in before exploding and damaging said opponents. Holding down the button can delay the explosion for a brief moment. The vortex also steadily deals minor damage over time.
The throwing animation ends before the grenade explodes, which means Sheik can perform in action around the time the vortex activates. This can be useful for positioning Sheik to tech-chase or combo an exploded opponent. Sheik can also be hit before the grenade activates. If this happens, the grenade will fall to the ground without exploding. This grenade can then be picked up and thrown, similar to Hand Grenade. The grenade deals 6-8% damage, but with no vortex.
This move appears to be completely original to Smash, as Sheik has never been seen using this move in any other game.
Special Move customization was added in Super Smash Bros. 4. These are the variations:
