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:
Bowser Capsule
(can't use on yourself)
Increases Bowser spaces and is
active as soon as it appears.

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.
