When I found out that with the gardening update we can plant rather weird stuff like Q'bthulhu eyestalks and tentacles, I just had to imagine how that'd turn out if it wasn't a game. You'd probably better not turn your back on them when they're about to become ready for harvest.

When you realize you misconceived the hint "requires special attention" when reading the instructions for those alchemy plants.

Now you know that planting eyestalks right next to tentacles causes some special Q'bthulhu symbioses...
