Warp Pipe (item)

In Mario Party and Mario Party 2, the Warp Pipe was the way to start the party. However, from Mario Party 4, it became an item to transport on the board. Whoever used it switched places with another player on the board via roulette. This made it the better version of the Warp Block.

In Mario Party 5, it became a capsule, where it could be thrown to a space on the board, or used on the player for 10 coins. It's effect was still the same as from Mario Party 4.

In Mario Party 6, it became an Orb that players could only use on themselves, but for free (it costs 10 coins at the Orb Shop, though). Again, effect was still the same.

In Mario Party 7, the effect was finally changed to roadblock from, where opponents who passed by the space containing the orb was caught by the Warp Pipe, and was sent back to the space he/she was at when their turn started.
