sentences:  Many of the game's puzzles and boundaries are based upon the abilities of Mario's partners, who each have a specialized skill required for progression in the game.The player accumulates partners as they advance into different locations; only one partner can accompany Mario in the overworld, although the player can interchange them at any time.These characters also assist Mario in the game's turn-based battles, where damage inflicted against them results in temporary paralysis as the characters do not have individual HP statistics.
