Shell Shield

Shell Shield is a special move used by Koops in the game Paper Mario: The Thousand-Year Door. Shell Shield can be used once Koops has been upgraded to the Super Rank and requires 4 FP to use.

Effects
To use Shell Shield, the player must press A button at the right moment to have Koops drop a protective shell onto Mario. If done successfully, an intact shell will protect Mario from three attacks without taking any damage at all. However, if the A button is pressed at any other moment, it will be cracked and won't last as long. Shell Shield can be a very useful defensive techique in battle as Mario can still attack with the shell still on him.

Trivia

 * Shell Shield works in a similar fashion to Sushie's Water Block from Paper Mario.
