So sad I managed to bring the plant to 0 hp, by wearing a gasmask and spamming electro shock slowly lowering its defense but then it hits 0 it just doesnt die. Took me a while to get there........
It's impossible to kill it. You need to go to the fairies hideout, give them a gift, and ask about giant plant. The queen will only accept cheese. After you give them cheese, one of the fairies shows you how to pass it.
