Bo wasn't marshmallow at first, he was actually human. He was also married to (before an event happened) Dawn. Happy couple, no kids tho. Then one night Dawn work (this will most likely change, as Dawn backstory needs to be added) sent her a message saying she needs to go to work. Bo wanted to come, but Dawn insisted him not. Then when she came back, she completely changed(to current Dawn). Bo asked her what happened but she didn't remember what. Few days later she couldn't eat regular food, but has no idea what she needed. Bo tried to figure out what she needed and found out. Souls. Since she needed to eat he offered his. Dawn refused and refused. Then she couldn't take it anymore and agrees, but because he wanted it. Dawn takes it, but she couldn't use it. Bo kept saying to eat it but she couldn't. Then the unexpected happens, the soul refuses to be put back. So Dawn just kept it as a little buddy. Bo went through an unknown thing and lost all his flesh and got it replaced. 1st com.
