My daughter is turning 4 years old next month and I want to throw a theme-based birthday party for her. I'd like it to be different this time. Any suggestions?

Ideally, you should ask your baby girl if there is something specific she likes. By this age most kids are articulate enough to share their feelings and communicate their likes and dislikes. If you don't hear anything from her, then you can try a bunch of themes. These could be a Dr. Zeuss party, Big Bird theme, angry birds theme, curious george theme, humpty-dumpty theme, candy land birthday theme, art and painting theme, treasure hunt, and even a circus theme. If your budget permits, you can even add a Photo Booth and a activities like paintball or pin the donkey or a colouring contest. Have something for the parents too, perhaps a corner for them to relax and engage with kids at at the same time.
