Keys

Keys are used in Mystery of Tyskie Islands as basic puzzle items. Six of them exist.

Ceiba Tree Key
Ceiba Tree Key also known as Ceiba-tree Key [sic] is a key made from Ceiba Tree wood. It is visibly put together in a ramshackle way from pieces of Ceiba Tree wood, and is mostly used for opening civilian doors, as it's mostly made at home by civilians of the Island Empire.

Claw Key
Claw Key is a key made from animal claws. It seems to be twisted from melted-together claws, has a large, rounded handle, and has a very sharp blade made from two large claws.

Locks it opens

 * Entrance to the Waterfalls (Beach, found after pressing the switch in the cave, revealing a secret part of a murky cave which you go through before)

Kaizok Key
Kaizok Key is a large, golden key with an universal likeness of the Kaizok - the rule of the Island Empire, represented as a crowned skull. During Pica's reign of terror, it was used by his Island Empire Revolta for locking doors in many buildings, such as the Digging Rig.

Locks it opens

 * Entrance to the large mine (Digging Rig, found at the end of the stealth section)
