impossible in 24 hours?

You should be able to do it fine. I started Milhouse on his task awhile ago and I'm a half an hour through Apu's task. Then just the final one (even with Homer, Marge, Lisa and Bart on separate tasks I still have 9 Toy Makers). I just got my Nativity Scene last night!! :D Too bad Bart is on a 24 hour task for Level 48 so there's no Baby Jesus in my Nativity Scene. If I was thinking I would have waited on sending him on that task. Oh well...today's gonna be a good day! We'll get the Fever Cabin AND Zutroy! I'm excited. :)
