Also known as baby dinosaur killers........
When my son was small he'd come into bed with me at dark o'clock in the morning. For a while he'd just lie and cuddle, but then he'd decide to play baby dinosaurs. This involved going, under the covers, down to the bottom of the bed and gradually "hatching" whilst making squeeky noises (can you see whats coming here?) After far too many mornings of being woken up at stupid o'clock I took my revenge

And that's why dinosaurs eggs stinked!
