Friendship Slot Item When this item is obtained, a slot machine appears on screen. Whatever 3 items are matched up will give the character who used said item a special effect or power boost for a short time. There is even a stat decreaser, which will alternatively make the character very powered-down for a short time.
Super Attack Card When this skill card is used, the character uses their super attack. These attacks are quite powerful and very useful. These are best when used to get out of tight situations.
Power-Up Cards Random cards that function as power-ups will appear randomly during battle. They can be picked up, and in the case of the picture below, transform the character into a giant for a select amount of time. There are many other status effects.
Stage Gimmicks Technically not an item, stage gimmicks exist in each stage for the players to use to their advantage. For example, the snowman in the snow level can be knocked into other players for some great damage. Other things exist in each stage as well. These stage gimmicks give a slight strategy flavor to the game that is otherwise just a simple beat-em'-up game.
