World 1-4
After fighting the second set of enemies, the player will find a branching path. To reach the secret exit, the player must clear more Light Orbs than Fire Orbs. However, the course does not contain any Light Orbs, so the player will have to bring an ally that can create Light Orbs. Upon defeating the boss at the end of the secret path, the player will unlock World 1-5.
