Iyokan

Iyokan is owned by Rx2 and SPE.

Almanac Entry
Iyokan is a pretty smart plant. He is so smart that even the scent of him eating makes people brainy, and his knowledge makes everyone feel like a textbook. Everyone is amazed by Iyokan. Well, except for the fact that he can give zombies a brain as well...

Strategy
Iyokans buff up your plant, and while they may be useless ITSELF, it makes other plants better.

Trivia

 * The Iyokan is pentagon, because of the actual fruit in Japan being reintroduced to promote "sweet smell of success in exams/Gokaku no Iyokan", a pun, and explains it's pentagon shape.
 * It only hits the zombies with it's scent every 5 seconds.
