After Green Devil found the key to the Witherdragon portal, he jumped through it, where he saw four large poles with beacons flashing red. Green Devil was a big, angry devil who could stand until his enemy was dead. In the floating world, knights that could teleport waited to attack whoever entered their world so when Green Devil entered, he dug a hole to hide in. He dug so far that when he got to the centre of the floating world, he collected a crystal that looked like an egg. He threw the crystal to the beacons and it exploded and all the knights fell into the hole.
