Staff at the caves believe the canny baa-baas were escaping the chilly weather and found a tasty bonus.
Thankfully for the tourist attraction the eggs suppliers have agreed to deliver a new supply by the weekend.
General manager Daniel Medley said: “The eggs were delivered at the weekend and somehow this ewe and her lambs got out of their usual accommodation and made their way in there.
“We think it was a bit warmer in there or maybe the smell of the chocolate attracted them.”
The woolly raiders may have looked cute and innocent, but the chocolate on their white fluff was a bit of a giveaway.
“Thankfully, our suppliers just laughed and have agreed to deliver some more before Good Friday,” he said.
“They are so cute that we couldn’t be too angry with them.”
