When a player dismounts an enemy rider, the rider's vulture lays an egg. Players must then collect eggs before they hatch into new, more powerful enemies. Hatched riders can still be grabbed safely until they have mounted their new ride.

Eggs are initially worth 250 points, but the more a player can grab without dying, the more each new egg is worth, up to 1000 points. The values are reset when a new level begins. Eggs caught in the air before they hit the ground or a platform score an additional 500.
