Neko Kago

Neko Kago are blue, metal cages that guard Cat Shines in the Bowser's Fury campaign of Super Mario 3D World + Bowser's Fury. They are impervious to all attacks, including those from Fury Bowser, and can only be destroyed by opening them with a key. If Mario or Bowser Jr. attacks a Neko Kago, it will only shake slightly.

Neko Kago appear near the entrances of Scamper Shores, Pounce Bounce Isle, Slipskate Slope, Pipe Path Tower, and Roiling Roller Isle, when the "Key to the Cat Shine" mission is available on each island. To obtain the Cat Shine inside, Mario must find the key in the surrounding area and bring it in front of the Neko Kago, either by walking into it or throwing the key at it. When the key makes contact with the keyhole, a short cutscene plays where the key opens the Neko Kago. Mario can then obtain the Cat Shine and complete the mission. After the "Key to the Cat Shine" mission has been completed on an island, if Mario leaves and returns, the Neko Kago will no longer be present.

If hacks are used to place a Cat Shine outside its closed Neko Kago, it still cannot be collected until after the Neko Kago has been properly opened. Additionally, if hacks are used to place Mario inside a Neko Kago, which is normally impossible, he is able to walk out of it. This is due to collision properties being applied only to the outside of the object and not the inside.
