From Sonic Retro
|First seen: Sonic the Hedgehog (1991)|
According to the original Western Sonic lore, Chirps was inadvertently responsible for teaching Sonic the Hedgehog how to perform a spin attack. While learning to fly, he tumbled head over heels out of his nest. Sonic teased the bird by imitating him, but gathered so much speed he was able to burrow into walls.
