I have realized that I have no frame of reference for what's normal for a penguin. I always just assumed vaguely knee height and now I am seeing these 2m adult penguin graphics (extinct, but...)
They're turning back into terror lizards. They're testing with penguins because they know humans will find it cute. Ten years from now when flocks of 10m tall ostriches are hunting us down, we won't find it as cuddly.
