Sabrina had been wandering through the maze of veins for a while and was begining to think she'd never find the way to her womb.
'This is taking forever!' she thought to herself. Just then she emerged into a largish domed room. This was even more bizarre than the sights she had already seen. Here there was grass underfoot, and nearby she thought she saw what looked like cows, and they were apparently having a conversation?! Shaking her head she walked over to them.
"Erm, excuse me," she interrupted, "But I appear to be lost! Could you tell me the way to the womb?"
"Moohuh? Hhhello dear." greeted one of the cows, "Lllost are you? Hmmmm..."
"Can you help? I really would be grateful."
"Wwwell dear, youre in your breasts at the mmmoment!" said the cow, "If you go down that way youll soon get there!". The cow nodded, pointing the way with one horn.
"Thankyou!" smiled Sabrina and headed off.
"Mmwho was that then?" asked the second cow.
"Nnno idea!" replied the first.
