When Lisa hangs her woolen clothes in the sun to air them out for winter, the hedgehog, to the amusement of the other animals, ends up wearing a stocking on his head.
Sonic travels back in time where he runs into his original, classic self and now these two Sonics must defeat their enemies, save their friends, and find out who is behind it all.
Just as Hedgehog is entering her winter nest for a long nap, a falling apple gets stuck on her spiny back, and her friends' suggestions only lead to more trouble until Goat finds the perfect solution.
