Maybe you should stick to plants. How bad can that get, right? (Now I’m leaving for the bank, the district cookie manager’s house, and the Petsmart, in that order ... before anyone brings up the kudzu fiasco ...)
Well, this spiderplant has been around since 1982 or so, and has repeatedly become a raging monster.
Add gene manipulation, and it could easily become a true monster.
Remember, I was trying to splice food crops with kudzu. Let Dark's at that particular database and we'll have part vegetable dust bunnies with tentacles that glow in the dark.
