Party G.R.E.N.A.D.E.

Source

 * This super common Loot card gives players a stack of Party G.R.E.N.A.D.E.S., complete with targeting circle!
 * Aim carefully at a glum group of characters and then throw your grenade. Everyone in the target circle will receive a one minute “buff” that causes them to dance ‘til there’s a smile on their face! Not only will all the targeted characters bust a move, they will also get to enjoy some streamers and confetti, making it a real party!
