The blacksmith has a large body and olive-green skin with a light blue dorsal fin. He wears brown clothing and a metal hat. He is Bikini Bottomshire's blacksmith.
He is mean when under pressure, but at other times nice.
While SpongeBob, Sir Patrick, and Squidly are traveling to Planktonamor's tower, they come across the blacksmith's place. The blacksmith grabs Sir SpongeBob, saying that he'll pay the rent when he needed to, but SpongeBob says that they were just there to get some armor. When the blacksmith realizes, he gears SpongeBob and Patrick to have armor.
When the blacksmith gives SpongeBob a sword, it's too heavy for him. The blacksmith says the only light weapon he has is a jellyfish net, but SpongeBob takes it. SpongeBob, Patrick, and Squidly all continue their journey to Planktonamour's tower.
