The Young Adult Prince
This guy is AWESOME! and he's HUGE!
Finally, an indestructible pet!
The Young Adult Prince is still a little smaller than his Dad, but he's getting a lot bigger! Luckily, he's learned to sit. Right-click him with a random item and watch for his tail to stop moving.
Right-click him with an empty hand, and you can ride him! Your very own ginormous three-headed dragon!
Use a diamond to un-grow The Young Adult Prince back to The Young Teen Prince.
BE CAREFUL!!!!!!! Check your OreSpawn.cfg file. Make sure FullPowerKingEnable is set to 0. If it isn't, well, then this guy can make his final transformation into the true King, the real King, and you'll find out why that is NOT A GOOD THING! Make a backup of your world if you enable this final stage... Seriously...
Lightning, fireballs, exploding ice...
Flying through walls.
Growing up into, THE KING!
How to Spawn
The only way to get this amazing pet is to defeat The King or find his egg in the Level 6 Challenge Dungeon! Tough choice, as it's almost certain death either way. And then, you'll need to be patient and raise him all the way up from a toddler!
How to Kill
Uh, you probably can't. And you shouldn't anyway.
