So Uncle Wiggily, folding back his ears in order that they would not get bent over and broken, began crawling down the rabbit hole, for that is what it really was. It was dark inside, but the bunny uncle did not mind that, being able to see in the dark. Besides, he could make his pink nose twinkle when he wanted to, and this gave almost as much light as a firefly. "No, this isn't the burrow where I used to live," said Uncle Wiggily to himself, when he had hopped quite a distance into the hole. "But it's very nice. Perhaps I may have an adventure here. Who knows?" And just as he said that to himself, Uncle Wiggily saw, lying under a little table, in what seemed to be a room of the underground house, a small glass box.
