Rebirthing allows players to unlock new islands. Each rebirth costs a set amount of coins, gems or Robux. The coin requirement increases with each successive rebirth.

Once enough rebirths have been reached, an announcement appears in the middle of the player's screen informing them of their unlocking of the next island. This announcement disappears after 10 seconds.^{[verification needed]}

Rebirthing also enlargens the player, maxing out at 60 rebirths.^{[verification needed]}
