Happy Grenades are thrown explosive items that inflict half the damage of an ordinary Grenade, and display a confetti effect. They must be acquired initially from a drop by the Party Girl when she is killed, although she only has 1/4 (25%) chance of dropping any each time she is killed. When the party girl respawns again, they can be purchased for 2 50 each, while you have them in your inventory.
- Happy Grenades are better suited to be used as a novelty item, as they do half the damage of normal Grenades and are harder to obtain. If bought from the Party Girl, they cost about three times as much as a normal grenade. To buy two happy grenades (which would deal a collective damage equivalent to a normal grenade), it would cost 5 , about seven times the cost of a normal grenade.
