Sonic

Sonic was a hedgehog who provided predictions on Hedgehog Day (which takes place on the same day as Groundhog Day) at the Kansas City Zoo in Kansas City, Missouri, in the mid-2010s.

Sonic's prediction was based on whether he saw his shadow or not during his Hedgehog Day appearance.

Sonic's name was likely a nod to the titular character in Sega's popular Sonic the Hedgehog video game franchise.
