The Shroomshock is a type of shock that posibly only Toads get. In this shock the character is so shocked he knocks himself out and is left unconsicious. The character that gets unconsicious well be knocked out forever unless he or she eats a Refreshroom.
This type of shock only appears in Mario & Luigi: Partners in Time. Toadsworth is the only character to get it, and he got Shroomshock when he was thinking that the princess was lost and unsafe.
