Bread penguins are pieces of toast shaped like penguins. If you don't believe me, the world will be irreparably changed. If you want to catch your toast turning into a bread penguin, you will need to be quick. It happens down in between the roasting field of the toaster, far from the peering eye. Watch your nose as you peek.
Mad scientists have bread penguins for breakfast. They are the only ones able to catch that brief moment of amphetamorphosis practised by bread. In fact, this is probably the real reason why mad scientists are mad. Their noses are all singed too.
