Nothing lets guests know what you expect from a party like a giant inflatable Fortnite Battle Bus.
My brother has bought his own bounce house, and his kids love him for it. I am not sure that buying this huge replica of the Battle Bus will work in the same way.
You can't bounce on it, you probably shouldn't jump on it, and you'll likely have more fun with a Llama Piñata, but…
Thats one huge inflatable Battle Bus.
Interestingly, the bus is cheaper via Amazon than Spirit direct.
