World 2-2 is the second board of World 2 in Mario Party: Star Rush. The board is a four-sectioned board, separated from each other by spike traps. This board introduces Peepa masquerading as allies; when allies spawn, a duplicate version of them appear as well. If players take the fake ally, the Peepa reveals itself, and it uses its Cursed Dice Block to either roll 0's or -1's. Players cannot select the Peepa, and the Peepa stays in the party until it eventually disappears. The spike traps function as they did in World 2-1; when players land on switches marked with a !, spikes either go up and down, and move if they are the same color. Spikes protruding upward act as barriers, and any players on a spike trap when spikes are released get knocked backwards. These two board features are additionally present in World 2-3. The board features four Boss Battles, and each of these take place in each section of the board.
