One thing to remember when playing with families - never accept the offer of a free vacation. This comes up when you have teens in the household. Occasionally it does seem to work, but mostly it just makes the game unplayable. Even modders haven't been able to fix it.
@CravenLestat mentioned making townies into Frogs, in one of my videos one of my witches got abducted by ab alien and she returned home she turned the alien into a frog.
A witch is supposed to like having a cat as the cat will make the witch more powerful - but my witch's cat had a problem and kept shredding her feet. They became enemies. Fun.
I have used a mod to make sure all of my babies get an imaginary friend. 100% of the time instead of the default 75%.
