you misspelled "unknown"

I got a txt file, it was about a boy who died...

the main details that attract my lore senses are that:

"He Was Buried Away From Home On A Smal Hill"

This could have a connection with Green Hill Zone.

"Skin Painted Blue And Somehow. He Was Still Breathing..."

This right here means that the little boy is connected to the sonic in this game, and the breathing could mean he's still alive.
