Appearing like the Marshmallow man every weekend, is the bright primary colours and dizzying heights of Inflatable World. This is basically crazy jumping land, with multiple enormous inflatable castles each with its own special power such as the giant Velcro wall where you get thrown in your Velcro suit at the wall. And get stuck.
Or the boulder cave where you thrust giant balls at whoever is brave (or dumb) enough to stand on the tower in the middle, the aim being to push them off.
Less violent, but still physical are the giant slides, the vertical cliff where you can jump off a great height, the basketball game, inflatable mazes and the enormous jumping castle where you throw yourself from hill to hill and try and not fall off.
Yes, the entire place is like some puffed up It's A Knockout, without the water and dodgy hosts.
Kids and adults of all ages are welcome at Inflatable World for a two hour jumping session. While the sessions are not restricted to particular start times (you can come at any time) you are meant to leave within two hours. I wondered how this was policed until one of the managers approached one of my children and asked to see their wrist. (On entry, every jumper received a band which has the date and time their session finishes.)
If the above sounds too much for your little child, fear not, because there is a separate room set up entirely for little kids. It was almost completely empty when we visited possibly because it was lunch/nap time and possibly because the little kids wanted to hang out in the BIG room.
Still, the small kids room is awesome in its own right they are still decently sized and there are plenty of options including slides, mazes and basketball all inflatable jumpy castles gone supersized.
There are a few things to consider firstly it gets hot. Each massive inflatable required continuous air being pumped into it, and all those pumps generate a fair amount of heat. Take plenty of water. Tie back long hair, and make sure kids wear shorts and t-shirts only. Skirts can be inappropriate (and dangerous) and long sleeves and pants can make kids get super hot really quick.
You have to wear socks to jump. No shoes and no bare feet. If you forget your socks, they sell them at the reasonable price of $2.50 a pair.
There are staff keeping watch over the inflatables to help and police but you can't just leave your kids and wander off. Children under 12 need an adult to stay with them and supervise.
And if you were wondering yes, adults can certainly jump (though I didn't see any adults jumping when we visited).
There is a kiosk on site that sells drinks and snacks. There is also a bar selling alcohol! You are allowed to bring your own snacks, but not meant to bring your own drinks (or presumably, your own booze).
One of the downsides is that it can be a bit hard to find. It's in the industrial part of Shenton Park, directly opposite the dog refuge and behind the bus depot. Look for the signs that say 'Revolution Sports' and 'Water Corp' and drive all the way to the back. There is plenty of parking. The building just looks like an enormous warehouse and isn't hugely well sign posted. Just follow all the other kids.
Inflatable World is also popular for kids parties, as you can bring all your own food and kids don't need any extra entertainment.
And the kids are guaranteed to sleep well that night.
