Round Eye the Dormouse
After the insects go the reptiles and the frogs. These are cold-blooded creatures, so they have no need to make a nest to keep them warm, but they don't like to be too cold, and always creep somewhere where the frost will not reach them. Bill the lizard sometimes goes deep down into a large grass-tuft, and sometimes creeps into a mouse-hole. Froggin dives into a pond and wriggles into the mud, or underneath a stone, and there sleeps under the water until the hot sunshine comes again, and he knows, by the feel of things, that it is time to be moving. Toadums prefers to sleep on land. He lies quite flat, with his hands in front of his eyes, and wakes up a little later than Froggin.
The Dormouse in his winter Sleep
He bunches himself up so as to close all the doors that the air can get in by, eyes, ears, nose, mouth, everything
After these the animals. Round Eye the dormouse goes to sleep about November. He builds a nest of leaves and grass all around himself, and, if the winter is cold, sleeps straight away into April. If the winter is warm, however, he may wake up and eat a little food, and if he is a wise little mouse, as he usually is, he keeps a little store of nuts and seeds at hand in case he does wake up. Prickles the hedge-pig does much the same. He has a nest which is even warmer, for, besides the leaves and grass which make the round of it, he rolls his spines into anything soft which will stick to them and so has a nice warm blanket next to his skin. Once he has dropped off to sleep he stays asleep till the spring comes. I don't think he ever wakes up like the dormouse, or ever makes a store of food.
Prickles the Hedge-Pig
The only other animals which sleep the winter through in this country are the bats, and some of them sleep even longer than the dormouse and the hedge-pig; indeed, they are only awake for three or four months in the year. Sometimes there are crowds of them sleeping together in old caves, and tree trunks, and places like that, and it may be that they half wake up and talk to each other to pass away the time. Indeed, if you know their hole and can put your ear close to it, you can sometimes hear them talking and squabbling—faint little squabblings like the sound of a kettle simmering on the hob when you can just hear the tiny bubbles hitting each other and bursting with bad temper.

He is not so tightly coiled as when he shuts up to defend himself
