If both Carl and Megan have an apple each, why don't they eat it?

Because Carl and Megan are butterflies and thay are saving the apples for their babies.

And you thought human babies were demanding. You should try feeding a family of caterpillars!

I tried feeding a pack of Hog Riders with ProtoType RadioActive Juice, and instead of them dying, they grew together, strong, strong enouygh already to defeat Winston Churchill of England, he shall surrender when I attack England!
