Ally Phone

The Ally Phone (originally named the Buddy Phone) is an item from Super Mario Party. It resembles a miniature mobile phone with an ally icon on its screen. When used, the player summons a random ally that is not already a character in play. The ally then gives the player the option of rolling their special Dice Block, as well as add either one or two to their leader's die roll.
