DD4 soon to by 5 (April) is in LOVE with Strawberry Shortcake! Ask mom/dad if there is a certain character she enjoys as it is widespread from Dora, Backyardigans, Spongebob, Little Ponies, Polly pockets, Princesses and more if you want to do a character gift.
Other great ideas are
*craft items - DD is starting to be interested in the bead kits - make bracelets, painting, coloring, etc.
* Big girl dress up stuff - lip gloss, light fingernail polish, fun hair accessories. Not to mention DD still really enjoys the "fake" stuff too - boa's, heels, purses, etc.
*some type of radio, tape player, walkman - a lot of character ones out there
*If she has a handheld game - Gameboy, Leapster, etc pick her out a game - many are about $20
* Boardgames - Chutes & Ladders, Candyland, Perfection, Connect Four, Checkers, Memory
* My kids get SOOOOO much that mom/dad really appreciate gift cards to the kiddos favorite spots - Chuck E Cheese, McDonalds, etc. or even the toy store so she could pick out some item that wasn't left under the tree. I know people don't like to give GC but sometimes it is a better idea than a toy that you don't know if she would or wouldn't like.
