Cthulhu is the dark lord of the depths. He rules in the city of atlantis, far beneath the sea.
He is big, and green. Some would describe him as a monster of vaguely anthropoid outline, but with an octopus-like head whose face was a mass of feelers, a scaly, rubbery-looking body, prodigious claws on hind and fore feet, and long, narrow wings behind, with a long tail. He is 8 blocks tall.
He looks like a green enderdragon with a green squid head. He is bi-pedal, men aing he walks on his two feet.
Def: 3 hearts
He wanders atlantis. He destroys all blocks but bedrock, obsidian, and atlantian gold. If you get within 5 blocks of his hand he will try to hit you. If you get within 5 blocks of his feet, he will try to step on you. Also, contact deals dammage.
best way to defeat cthulhu is to use a bow. Especially if it is enchanted with infinity III and Homing III
When cthulhu is killed he drops 5000xp, and the Necronomicon.
