34295: Handle Sparkle
The handler for the sparkle (sprite IDs 88 to 91) that appears when a creature is created by SpawnCreature. The counter at offset 14 of the entity starts at 32 and the sprite is chosen from its bottom two bits to animate the sparkle. When the counter reaches zero the sparkle turns into the creature that is held at offset 2.
