>>7217001>>7216996>>7217007in my case pretty much what
>>7217004 says. What it was called largely depended on what it looked like, generic looking ones with no discernable features would be called both ways but if it was an obvious castle like pic related, everyone called it a Bounce/y Castle.
but if it was some really big one at an amusement park, it was usually called moon walk, moon bounce, or something along those lines, because the park itself choose the name and it had a sign and everything.
