Like a bad Penny

Penny, used to be called Pi, as in life of, not the infinity project, anyway a very skinny militia sheep who spent 3 month hiding in our field and despite best efforts from the K9 clan and yours truly steadfastly refused to be moved on to pastures new.
Since then she has teamed up with our last remaining Ryeland, Snowy and the pair wreck havoc as only a woolly duo can. Until the other day when she went missing presumed pie filling. She turned up late at night causing mayhem as any sheep of worth would when announcing her arrival back at Rock HQ where 23 sleepy K9's were waiting.
Today she has reappeared after disappearing from the safe place where no pie makers are allowed, Goatanamo, where she was fed and watered regular with Snowy. Clearly this was not to her liking and proving the rule of smallholding, animals will get through a hole half their body size, she did. But today shes back again. Like a bad Penny. Hence the name change.
