This looks like so much fun

I'd be scared of suffocating somehow

This is something I want to participate in, where is it? Is there a weight restriction?

It's fun until one of those plastic bubbly things breaks and someone falls to their death.

What if it pops and swallows you whole?

Where is this I need this

Imagine this in a zombie apocalypse.

This looks like one of my nightmares. You know the ones where your being chased but while trying to run away you end up on something like this that seriously impedes your movements. You try and try to get away but the thing (whatever it is) gets closer and closer and you're stuck on this desperately trying to gain ground. You're flailing, sliding, rolling, you can't get your feet under you or get enough purchase to get away. It's there, it's right there, you're going to be caught. It's right behind you. It's............... Well I still think this would be fun to try out in the waking world.

It looks HORRIBLE! I imagine struggling to climb but sliding down farther...farther...until the plastic,surrounds you and you can't breathe.
