Rascal's Treasure Chest Kit

Rascal's Treasure Chest Kit allows the player to place (using a target reticule) an Innocent Looking Treasure Chest on the ground. Any player at all may open it. There are two possible outcomes:
 * the 'trick' - the chest emits a Holy Nova-like visual effect.
 * the 'treat' - the chest shoots several fireworks of different kinds into the air, which proceed to explode into different patterns.
