Warp Block

The Warp Block is a block in the Mario Party series, that when used, will transport a character who hits it to another character's space. In turn, the player that they travel to will then be transported to their initial spot. In Mario Party, it can be bought at the shop, and when turned on, it will appear in a random space to be automatically used when the player stops on it. In the other games, it is a buyable item that can be used at any time. It appears in Mario Party, Mario Party 2 and Mario Party 3. It is Yoshi's favorite item.

In Mario Party 4, the Warp Block is replaced by the Warp Pipe, and has been its successor ever since.

Mario Party DS has an item analog to the Warp Block, called the Warp Dice Block. It doesn't switch the character who used it with another character. Instead, it lets the user warp to a random space.

A block with a very similar function to the Warp Block appears in Mario & Luigi: Partners in Time. In this game, it is known as a Pipe Block. It is blue and has a picture of a Warp Pipe on one side. When Mario and Luigi's (or Baby Mario and Baby Luigi's) younger/older selves are too far away, if one pair hits a Warp Block, a Warp Pipe will appear and shoot their companions out.
