Skiing or skating?

Neither skiing nor skating. Instead sliding :)
I was walking with Caspar downhill, on a path. We had enough grass so we could walk stable.
Then we came on a muddy tarmac road. Still going slightly down. But the wet mud made it so terribly slippery, that Caspar couldn't walk, not even stand, but slid a couple of metres.
In my entry you can see how he tried to stabilise himself again, with his massive paws going left and right.
