When Dennis sleeps the lights are on but nobody's home! He looks totally zoned out and doesn't even flinch when I try and pick him up. He is usually quite quick and scarpers and soon as he sees my hand go anywhere near him.
Piggle does this a lot, I've never seen her lie down properly or close her eyes, or sleep for any length of time- she power naps for a few minutes and kind of switches off with her eyes open then starts leaping about again. Nobody likes to share a pigloo with her because she wont settle down, and the other piggies all like their zonked-out chookened chillaxed sleepy time... she runs round all night tipping any sleepy piggies and their furniture upside down!
