That's so great you found him, I'm so glad for you.
My first two corns were left at my highschool when I was a Jr and they got out one day. Cream (snow) was found shortly after in the same room. Peach (Amel) was found a week or two later on the other side of the school in the boiler room. Thankfully she was unharmed and probably had her fill of mice because our school had them everywhere.
