I couldn't decide between bob the builder and blues clues for my son's second birthday party so I decided to do both and called the theme "bob the Builder Meets Blue". For the invitations I used my digital camera to take a picture of my son's toy of the bob the builder guy and I stood his zipper pull blue next to him and took a picture close up with a green background of the two of them together and put it on the computer, then I printed out invitations which said "Bob the builder meets blue". For decorations I did red and yellow streamers and dark and light blue balloons, a Bob the builder happy birthday sign and a table cloth with tools and paw prints on it. I also made paw prints on the floor. I did half of the loot bags blues clues and half bob the builder and filled all of them with a combo of blue things and bob things such as tools, bob the builder notepads, blue stickers and zipper pulls and bob the builder bubbles. I printed coloring pages of both for the kids to do. For the cake I used the bob the builder stamp set with bob the builder background and put a blue zipper pull on the top next to Bob and Wendy. I had construction hats for the boys and blue headband with ears for the girls. The kids had a great time and it was different. So if you can't decide what to do you can always do a combo like I did.
