Today I had two Sims defeat the Mother Plant for the aspiration - and NOT by doing the story twice, either. Basically they levelled through the story side-by-side, and shared the Scanner, and pulled off the final battle twice in a row. It helped that one of them had the Book Of Life. The story is great for levelling up your Logic skill.
I also have planted a couple of Bizarre Fruit and something occurred to me - think you can make Fizzy Juice out of Bizzarre Fruit? Switch StrangerVille into High Weirdness, and just wander around harvesting the stuff.
