When landing on a Bowser Space in Mario Party 5, there's a very small chance Donkey Kong will interfere with the cutscene, striking Bowser and saving all the players from the current encounter.

The Bowser Capsule is automatically used when obtained so the description for it is never seen. However, there's a description for it found in the game's code. The description says this:

The "Coney Island" minigame pays homage to New York City's Statue Of Liberty. The minigame takes place atop a statue of Mario holding an ice cream cone upward.
