As far as where Huygen's actually landed...
....the scientists in charge of the instrument designed to penetrate
its surface, and measure penetration resistance, have concluded
that the surface where Huygen's landed is like a thin hard crust over
a material with the consistency of wet sand, down to a depth of six inches.
"It's like Creme Brullee" [thin hard crust over a squishy filling], one of them said.
Squishy? - That's wet enough for me.
