Shell Slam

Shell Slam is an attack that Koops can use in Paper Mario: The Thousand-Year Door. This attack is only unlocked after the player has leveled Koops up to the Ultra Rank, and costs 6 FP. This attack is a more powerful version of Power Shell.

To successfully execute this move, the player must rapidly tilt the control stick left. Depending on how well the player does, the damage can be anywhere from 0-6 HP against all of the enemies, piercing enemy defense. This attack is very similar to Parakarry's move Air Raid, from Paper Mario.
