Cowplant is kinda cute tho (minus the killing of sims anyway) 👀
In The Sims 2, reaching level 6 of the natural science career meant that you could be awarded the cowplant. He looks deadly but he's a real softy (until he starts eating sims of course).
This was one of the only real reasons to go to university in The Sims 2. You needed a degree to unlock the career that gets the cowplant!
