I have that same little log hide for one of my corns!

I just switched my larger corn over to newspaper and she doesn't seem to happy about it, its always a mess now. I keep my smaller one on aspen and she loves it, if they mess that up its not too hard to just stick your hand in there and flatten it back down.
Usually my boas and pythons are the ones that mess up the water dish and destroy the cage like that, maybe get a heavier (ceramic?) water dish for the snake so it cannot tip it over.
