Crabclaw

The Crabclaw (トレジャーオブシー) is a Keychain for Sora's Keyblade which appears in Kingdom Hearts and Kingdom Hearts: Chain of Memories.

In Kingdom Hearts, Ariel gives Sora the Crabclaw once Atlantica's Keyhole is locked. In Kingdom Hearts: Chain of Memories, the Crabclaw is the signature Attack Card for Atlantica.

Design
The Crabclaw's handguard is purple, and resembles a pair of mermaids, while the blade resembles a jet of water. The blade's teeth are shaped like a crab, with its claws pointing outward. The keychain is attached to a green lobster on the handguard, and its token is a blue seashell.
