In the Smash Bros. Unlimited version of the Mushroom Kingdom stage, players sent flying to a possible KO may be stopped in their tracks by the various Brick Blocks or ? Blocks scattered about the area. When hitting a ? Block, it'll spawn a random item. A Bill Blaster also appears on the stage, firing Bullet Bills every 3-5 turns which might hit a player. It may also fire a Missile Bill, which first appeared in Super Mario Bros. 3. Missile Bills will home-in on a random player and target them. Koopa Troopas will appear on the stage randomly, jumping on one of them will cause them to retract into their shell, creating either a Green Shell or Red Shell item. Goombas will also randomly appear on the stage, and by jumping on them, they'll simply be defeated. Touching a Koopa Troopa or Goomba in any other fashion will result in being damaged.
