No one could touch the floor but we had to somehow make it to the kitchen to save the dog from the various invisible evil creatures that live in the lava. The dog seemed to walk around with no problem in the lava, and even though the kids tried to save him, he didn't stay on the rocks (pillows) for very long. There was a lot of screaming and running around, accidently falling into the lava. The dog went from innocent victim to terrible child eating lava shark in less than one second.
It may be sad that this was the highlight of my day, but I thought this was one of those days with my kids that even the dog won't soon forget. I LOVE imaginary play!
