Batman party Invitations had the Batman search light saying "Batman needs YOUR help" Inside said "Celebrating Joey's Birthday!" Decor: Black streamers ALL over. Balloons and bats. We had big questions marks up the walk way from the Riddler. I bought black material at the fabric store (really inexpensive) and cut out capes, attached ribbons to tie them on each child. We had Batman tablecover. We also had one of the movies playing while everyone arrived. We couldn't find a Batman piñata, so we made one in the shape of the insignia. Time consuming but it got the kids involved days before the party. Food: We had a Batman cake with "poison ivy" punch and Mr. Freeze ice cream. Music: We didn't have any. There were too many kids. Activities: We decorated the capes, played pin the bat on Batman, had the piñata, opened present. They had lots of fun all being "different" Batman's. Goodie Bags: Candy from piñata, blow outs, Paper Batman masks, parachute guys, Batman rings, and their favorite sticky guys.
