Bipolar Pea

Bipolar pea shoots fire peas backwards and frozen peas forwards. The head on the back shoots at the same speed as a repeater. Basically, the first head is a Snow pea and the other one is a Flame Repeater

Suburban almanac entry
Bipolar pea is bipolar. He makes pole vaulting zombies freeze, and when they jump over it, he sets them on fire. Nobody knows why he is so cruel with jumping zombies
