Sobber :)
 

But that would damage the poo, making it difficult to play with...

You couldn't mould ducks & little people out of poo that's got too hot...

I've tried! It just crumbles. Moisture must be retained

The only "sobber" here is me for even clicking on a link that can't spell "sober".

DaFuqk!

:Oh crap

I've used one of these a long time ago in Upper Michigan during the middle of winter.
Seats warm.
