The Koopa Kabana is a hotel located within the Koopa's Seaside Soiree board, found in the game Mario Party 4. The name is a pun on Copacabana, a beach in the Brazilian city of Rio de Janeiro that also appeared in Mario is Missing!.
If the player passes over the Kabana Space, a Koopa Troopa will ask them to invest five coins to start his Kabana, and then an additional five coins each pass to continue building it up. This makes it very similar to the Koopa Bank from the previous Mario Party games. The more coins that are invested, the more pristine the Koopa Kabana looks; however, if a player lands on any of the Happening Spaces near the location, they will be forced to pay for a one-week stay. The price will always be total amount spent on the Kabana up to that point. After Koopa Troopa tells them to enjoy their stay, a tsunami will demolish the Kabana, restarting the investment process and wasting that player's coins.
