 * Desc:   When an enemy is in the frozen state it needs to 'sparkle' small
 *		   sparkly animations appear around the enemy one after the other. Thats
 *		   what this entity does, it can be applied to an area and it will make
 *		   the sparkly effect appear as long as the parent entity is in the frozen
 * 		   state.
 *
 * Usage:  Used by the _enemylib.zes script
 *         
 * Sprites: _weaponsheet.spt
