Chris met Sonic when the hedgehog was drowning at the bottom of Chris' family pool (due to the fact that Sonic cannot swim). After befriending him they went on multiple adventures together and had a practically unbreakable bond. Eventually, when Sonic had to go back to his homeworld to prevent the two dimensions from merging, Chris turned off the portal before Sonic could go in and ran off with him, unwilling to let his new friend go. Chris had some sense talked into him by Sonic and he was last seen being carried off by Sonic back to his parents before Sonic went home.
