My daughter wanted to have her fourth birthday party at Chuck E Cheese's.  To make the party special since all Chuck E. Cheese parties are generally alike we decided to have a yellow party since that is her favorite party.  I bought yellow invitations and punched a whole in them.  Then I attached them with curling ribbon to a yellow tee shirt.  On the invitation I asked each child to wear the shirt attached. The parents received yellow smile face buttons so between the tee shirts and the buttons everyone knew who belonged to our party. When guest arrived they were handed a yellow smile face coin holder filled with tokens and a small yellow bag decorated with smile faces bag to hold their tickets. I bought both of them at Oriental Trading. The nice thing about Chuck E. Cheese is that the hostess will set up for you but you can bring your own party things so while the kids were playing they set up the partyware I had purchased: smile face tablecloths, yellowplates and yellow and white striped napkins. I had also bought yellow smile face balloons and they tied them to each chair.  For centerpieces I made bouquets out of yellow lollipops with extra-long sticks and artificial flowers and put them in small bright yellow shopping bags.  The lollipops were decorated with yellow ribbons which were printed with my daughter's name and birthday info.  After the kids had their pizza and Chuck E. came out and did his show, we had the cake which was a yellow smile face. I bought yellow smile face hats and blowouts for this party and the table looked great.  After the cake my daughter gave out the lollipops in the centerpieces to the parents and we handed out the goodie bags which were clear yellow smile face bags with all yellow candy (banana now or laters, pineapple lollipops and and lemonheads) and small yellow toys. It turned out to be a very pretty looking party and since it was a Chuck E. Cheese party it wasn't really alot of fuss.  Everyone complimented me on making it a special and different party.
