the park no cleaning of the floors and such. birds will eat it and there are plenty of things to play with take a trash bag paper cups plates etc. invite 8 expect 3 or 4 osme parents cant get kids there due to work etc. get a cake with play vehicles on it trucks , fire trucks, cars etc. but then on the presents I would do a baseball bat and glove or whatever sport he likes. or put animals on the cake. little plastic ones. and get trucks and sports for gifts. why base it on just one thing. or like with mine he likes cars animals and cowboys. his cowboys ride motorcyles and horses so in his case a truck with a horse trailer a horse and a cowboy. you can mix and match. no reason you have to do just one or the other.
