Combat Items
These items are used against enemies.
 * Fire Burst: When used, every enemy visible on the screen bursts into flames. The effectiveness of the Fire Burst depends on how vigorously the player shakes the Wii Remote up and down while performing the attack.
 * Shell Shock: Rams into enemies when kicked.
 * Pal Pills: These cause a group of miniature 8-bit Marios to follow the player around and act as a personal army. (Coincidentally, a similar concept appeared in the Super Mario World cartoon in the episode Rock TV, where Yoshi and the Princess distract King Koopa and his cohorts by hitting a block which expelled a dozen tiny, mini-Marios.)
 * POW Block: Summons a POW Block, which when activated hits all enemies on screen.
 * Thunder Rage: Similar to the Fire Burst item, this sends strikes of lightning to greatly damage all enemies shown on the screen.
 * Shooting Star: Showers enemies with stars causing them damage.
 * Catch Card: A card that catches an enemy's soul. If it works, damage to that enemy is increased.
 * Catch Card SP: A card that catches an enemy's soul. It has a higher chance to catch an enemy compared to a regular catch card.
 * Volt Shroom: A shocking shroom that briefly paralyzes enemies the player comes into contact with.
 * Ghost Shroom: goes around attacking enemy that are on screen.
 * Hot sauce: Temporarily doubles your attack power.
 * Courage shell: Increases your defense temporarily.
 * Ice storm: When used, every enemy visible on the screen is damaged and gets frozen if it survived the damage. The more you shake the remote the more damage it does.
 * Sleepy Sheep: When used, all enemies on screen fall asleep.
 * Stop Watch: Freezes all enemies on the screen.

Special Items
These items power-up the player's character.
 * Mega Star: Causes the character to grow to immense size (similar to the Mega Mushroom in New Super Mario Bros.), allowing him or her to crash through the level, effectively invincible. It also causes the character to appear in the form of a NES-style sprite.
 * Speed Flower (a variation of Fire Flower): Deviating from its traditional role of allowing Mario to throw fireballs, the Red Flower speeds up time.
 * Slow Flower: It causes Mario and the enemies to slow down temporarily, but gives three times the points when an enemy is defeated.
 * Happy Flower: This item takes the shape of the Flower Points (FP) in the previous Paper Mario games, and when touched, will send coins raining down on the screen for a limited time.
 * Turtley Leaf: Reduces all damage to the player by half.
 * Block Block: Allows you to be temporally be invincible.
