Casameownca

Casameownca (Japanese: カサブニャンカ Casabnca) is a dungeon in Pokémon Super Mystery Dungeon that could only be accessed through Meowth Theater.

Prior to entering the dungeon, the party's levels will temporarily be set to 5 and all items and Poké will be sent to the Deposit Box. After the undefined finishes the dungeon or faints on the way, the related Meowth Theater film is stored on the SD card and could be sent to other players. On August 30, 2017, an update was released that disabled Meowth Theater, removing the ability to access the dungeon.
