After the kids ate dinner the real party began. I had arranged in advanced for one of our local police officers to come and send a message from Police Comissioner Gordon. When the officer walked in he told the kids that Comissioner Gordon had sent him to wish Landon a Happy Birthday and that he had Batman and Robin on the job of finding the birthday cake. The police officer told the kids that they were about to be trained as superhero's so they too could help find the missing birthday cake. The officer said that he was sent to talk to the kids about how a superhero should act, things like obeying, sharing, being respectful, etc. When he finished his talk, much to the kids surprise in came Batman and Robin running in. They called Landon to the front of the room and said that they were here to train the party goers to a special superhero training so they to could help find the cake. At this point the kids walked through the Gotham City entrance and found a room lit with black lights and clouded with a light fog (provided by a time delayed fog machine). Prior to the party I had arranged with a local toddler gymnastics teacher to borrow several pieces of her gymnastics equipment (mainly mats, wedges,a mini trampoline, etc) to lay out in Gotham City to use for our superhero training. Under the black lights the gynmastics equipment glowed in the dark and made the room really look like a cave. My husband used a small garage spotlight with a bat taped over the lense and shined it on the wall to look like the bat signal was being shown in the sky. Once inside Gotham City, my husband had cut from large sheets of card board the city sky line and painted it black, them outlined it with Christmas lights. Entering Gotham City was the highlight of the party!! At this point Batman and Robin proceeded to show the little superhero's using the gymnastics equipment what kinds of things a superhero should. They covered things like rolling, jumping, climbing up wedges, scooting through a mesh tunnel- it was great fun and the kids loved climbing around with batman and robin. Once all of the kids had an opportunity to use all the pieces of equipment we left Gotham City and went back into the party room where batman and robin awarded all of the children with a superhero certificate of achievement and a bat cape.
