List of Mario Party: Island Tour pre-release and unused content

This is a list of beta elements in the game Mario Party: Island Tour.

Stages
On Perilous Palace Path there were no cows, and a Blue Toad can be seen next to the cannon. Whomp does not appear at the end of the course. Multiple Banzai Bills could launch at once in Banzai Bill's Mad Mountain and when Banzai Bill passes by, the players run back to the start instead of flying back. The design of the Comet Observatory on Rocket Road was also much simpler, lacking all Domes.

Items
Originally, on Perilous Palace Path, characters used cards as items. However, in the final game, generic items are used instead.

Spaces
The Piranha Plant Space had a different design, having an abstract picture of a Piranha Plant rather than an actual picture of a Piranha Plant. The green-coloured space that marks the midway point of Banzai Bill's Mad Mountain was black and had a design with a red Banzai Bill and a double-headed arrow underneath it.
