Your fall is broken by a pile of fruit, and you landing on them crushes a bit of juice out of them. Getting up and looking around, you find yourself in a vast cavern full of food!
There are a few glazed hog roasts, decorated with exotic fruit, several pies, tarts and a huge cake, also decorated with fruit.
"Why don't you help yourself?" comes the sinister voice "This feast is all for you!"
"How do I know you haven't poisoned it?" you ask
"I give you my word it's not. It is very delicous, though. So delicous that you won't be able to stop eating once you start!"
You frantically look around for an exit, but there isn't one - apart from the hole you fell through, way out of reach.
You have only two choices it seems. Eat until you're obese or starve. Hobson's choice, really.
