Joke's End is a frozen palace in the Beanbean Kingdom. The only route to Joke's End is via surfing across Oho Ocean using Luigi in surfboard form or by using a green Warp Pipe. Mario and Luigi travel to this palace during the events of Mario & Luigi: Superstar Saga and Mario & Luigi: Superstar Saga + Bowser's Minions. Joke's End is inhabited by Jojora and her friends; despite one line of dialogue stated by Jojora[1] suggesting that there are or have been more people living in Joke's End, they seem to be its only occupants, besides a single Beanish character, presumably a visitor, seen on the entrance staircase. Keeping with the theme of locations in the Beanbean Kingdom being named after laughter sounds (Chucklehuck Woods, Teehee Valley, Hoohoo Mountain, etc.), Joke's End is also known to be a graveyard for bad jokes, though none of these dead jokes are seen. Throughout Joke's End, Mario and Luigi often must split up to solve puzzles and progress.
The palace is almost entirely made of snow and ice, resembling the Crystal Palace from Paper Mario. Its design includes several statues of Beanish-esque characters giving horrified looks; these monuments may be headstones for the palace's aforementioned and unseen dead jokes.
The final green pipe in the game, #9 (#13 in the remake), is located at the entrance to Joke's End.
The Save Album areas include Joke's End First Floor, Joke's End Second Floor, Joke's End Third Floor, Joke's End Fifth Floor, and Joke's End Reception Room.
