Dear Faith, The Big Ol Bouncer is a lot like the Magic Castle Ultra 12. Boast inflatables boast a 12 foot bounce platform, room for 6 kids at a time, and can hold up to 100 lbs per user, 600 lbs total. What makes these two items different, other than the color, is the design. The Big Ol Bouncer is shorter, so it can be used under most ceilings, while the Magic Ultra 12 is a bit taller, and has a wider slide. Sincerely, Blast Zone Support
