Spidine

A Spidine is a hybrid of a Sardine and a Spider. Players can create spidines in Creature Creation, in the basement dungeon of the Tower of Life building once they complete the Tower of Life quest.

A spidine is created by a player using one set of Red spiders' eggs and a raw sardine on the spidine altar of life in the dungeon and then activating the altar (found in the south-east part of the basement). The Homunculus in the dungeon then creates the monster, which appears near the altar and will attack the player.

Trivia

 * Its examine seems to be from the Spider-Man theme song - "Spider-Man, Spider-Man, does whatever a spider can."
