It's official, you and Sonic the hedgehog are parents. For the time being that is. It all started when you and Sonic went from having a nice chat and walk to having a "friendly" competition which caused Sonic to get competitive and show off and then ended with the blue ball of spikes in question, crashing into a Chao garden and accidentally injuring one of the little Chao. Feeling absolutely horrible for your reckless behavior, you and Sonic step in to nurse the Chao back to health. You return back from finding fruits to feed your little Chao and leaving it in Sonic's care. However when you return you find the blue devil in question is lying face down in a pond while the bandaged Chao is sitting peacefully on his back. Sonic lifts up his head to deadpan at you.
"Took you long enough. This kid can't stay still for one second!" He exaggerates as he lifts himself out of the pond and walks out carrying the Chao in his arms.
