There couldn't be a more unlikely creature than the Penguin, aside from the dinofauxs that supposedly created the species.
Have you ever taken a close look at a platypus?
Yes, and as laughable as it is, somehow the platypus has a better evolutionary record than the Penguin. I wouldn't rule out the Platypus being an early attempt at creating a walkable lunchbox though. Naturally, they wanted red meat and eggs, but weren't prepared for half of them being poison due to their meddling. This also explains their anomalous bones, jaw, and other silliness.
