Mario Party DS is a party game developed by Hudson Soft for the Nintendo DS. In this installment, Mario and friends are miniaturized by Bowser as they seek to reclaim stolen crystals. Players navigate through oversized environments, challenging classic Mario foes while collecting coins and stars. The game features a single-player campaign across five themed settings, each culminating in a boss battle.
He's captured Mario and his friends in his pursuit of a crystal that the group collected when it fell from the sky, and he doesn't hesitate to shrink them to miniature size to get rid of them and get his hands on the other four crystals. The mini-heroes have to find the crystals before he does, making their way through giant environments filled with enormous creatures. The single-player campaign takes place in five different settings, each of them ending with a boss. As usual, players have to collect coins and stars, at the same time escaping dangers such as Piranha Plants and other classic creatures from the Mario universe.
