I've actually been wondering this

So it's just as well that it happened. Good thing I saved before, though.
-D: What was it?-
Shed Your Skin works the second it starts to get dark outside -- 6:00 sim time.
-D: Oh.-
I wasn't sure. I'll cast it in the afternoon next time. I hate to torture VampDoc with snakes, but I need the shot.
-VD: I thought I saw something new in front of my house.-
Oh, yeah. You got another growth. A Root of the Problem.
-VD2: A Root of the Problem? I thought those were bad.-
May or may not be. At least now I can try for a nice little crystal. You can definitely do enough magic. I should hold another little party soon. . . . But first I need to make more Relationship Boosts, maybe an Enchant. I love this family.
-D: *pretends to pout* What about me?-
I love you too. I need to make you make more magic. Use your Smiley Faces. And of course I need the people in OddsNFriends to learn Magic. So far, Tracie and Candace are the only ones taking full advantage of it. I should give SimLisa a spell for her birthday. *grin*
