Blood-shroom

Blood-shrooms are offensive mushrooms that go into a damage and health increasing frenzy when they've taken out enough zombies.

Overview
Blood-shrooms shoot small red pustules at zombies that normally deal 1 damage point. When a Blood-shroom has defeated 10 zombies, however, they get an increase in health (now 10 ndb) and an increase in damage (now 3 damage points). If the Blood-shroom does not vanquish a zombie in 15 seconds after transforming, it will revert to normal. It will now require only 9 defeated zombies to go into frenzy mode again. The amount of zombies required will go no lower than 3.

The Blood-shroom is based on the Hydnellum peckii, or the Devil's Tooth.

Plant Food Ability
Using Plant Food on a Blood-shroom will cause it to unload a barrage of blood pustules, as well as causing it to go into a permanent frenzy state.

Trivia

 * It does not sleep during the day, but instead requires 15 zombies to be defeated in order to go into its frenzy mode.
