Shell Shield



Shell Shield is a defensive move that Koops can learn in Paper Mario: The Thousand-Year Door. Koops learns this move as he levels up to Super Rank. Four FP is required to use this move. To successfully use this attack, the button must be pressed when the cursor is close to the center of the gauge. Depending how close the cursor is to the center, the shell will have two to eight HP. The shell will cover Mario and take damage up to its max HP for him. The only way to see its HP is to equip the Peekaboo badge, as it is not possible to use Goombella's Tattle ability on the shell.

There is a glitch in the game that affects this move. If Mario is hit by an attack that does not do damage, either due to Mario's defense negating the damage or the player guarding with the action command, the move's action command becomes bugged. The action command still functions as intended, however the audience will always react as if the action command was missed, resulting in very little SP being restored and audience members leaving. This also causes the "Good!" or "Great!" messages to not show up, even if the action command was executed correctly. The glitch is fixed if Mario is hit by a move and takes damage.
