A woobee is from when you're little or when you're older, something that made everything better when you had it with you. Something that you looked at, held, listened to, saw that made you feel safer or less upset or made you happy. Torey needs to calm down at this point in the book because he's getting so worked up over everything that's been happening with Bo involving Chris Creed.
I used to have a woobee when I was younger, and it was my blankie. I still have it in my closet but I don't really use it anymore. I have a new woobee for myself now that I'm older. I have a bear that I have to sleep with every night and it helps me fall asleep. It used to be my Aunt Kathy's bear but I took that when we went to her apartment to clean it out.
