About Sonic X
Sonic X is an anime series and also known as the 'Sonic Project'.
Sonic the Hedgehog (you might know him from games like 'Sonic Advance')
is the main character.
The Story:
Due to an accident at Chaos Control Sonic and his friends are transported to
another world: Earth. Sonic lands into the swimming pool of Chris and Chris
saves him [yup, Sonic can't swim]. Amy, Tails, Cream, Cheese and Knuckles (^^)
are in the same city too and stay [except Knuckles] in Chris's house.
They try to find the Chaos Diamonds to get home.
Dr. Eggman is looking for Chaos Diamonds as well [maybe to destroy the world? XD]
