I had a Wrinkles dog who used to turn on by himself...I would be sound asleep and all of a sudden awoken to the noise of him crying or "eating" a bone or woofing the tune to London Bridge is Falling down...he has had his batteries removed for the best part of 20 years now...no talking for Mr Wrinkles.
Lily Lightly is a lovely pony, I hope you manage to track her down as others have said she only lights up...no chatting!
