Christmas ideas for my 4 Year old

My kids have everything.  Mia has a trampoline, kitchen, doll house, table and chair set, bike, scooter, etc.  I need cheap and unique ideas for her this year.  Here are a few ideas that I am considering this year. 

1.  Pillow Pets Dream Lights  Mia is afraid of the dark and she loves rainbows and horses/unicorns so this is a must have!
2.  The Moon  Who doesn't want to give their kids the moon?  It is extra special because Chris calls his mom (or vise versa) whenever the moon is especially pretty.  He is now passing that tradition on to our kids. 
3.  Tulle Canopy  Mia wants a rainbow room, but she may have to settle for a rainblow canopy.  Hopefully, my talented friend Carol can make one for her.
4.  Doc McStuffins Check up Doll  Doc is her favorite show
5.  Barbie Popstar Guitar-  She loves watching Barbie Princess Popstar
