Hollhydra

Hollhydra is a plant with 3 heads, taking up 2 tiles space. all 3 heads shoot holly berries that deal 1 damage each at intervals.

if a zombie eats the hollhydra, it will only eat one of the heads. if the zombie is then defeated, the hollhydra will continue shooting, but only with twofold projectiles. if the last head is fully eaten, the zombie that ate it will become poisoned, and take light damage over a short period of time.

Trivia
