What a delightful place for a dog to poke around. Full of aromas no doubt. The textures you've added are great, and contribute to the sunshiney-spotlit effect. I don't think I've ever seen a wombat hole, but they must be pretty big. Someone survived the Victorian bushfires by hiding in one.
Each night Katee would slip out while the rest of the family were watching tv, and add to her tunnel - she had dreams of travelling the world, going to far off places where the weather wasn't so hot and the people weren't always so darned cheerful.
She had heard from the other dogs that if you tunnelled far enough you would reach a place called 'ingerlland' where the weather was dull and rainy, buses were red and people said things like " . . mustn't grumble . . " whilst grumbling anyway . .
Katee had to find out if it was true - or if the other dogs were just pulling her leash . .
