Find Ron Weasley hidden somewhere in this Womping Willow(yes, I know it is not really a Willow Tree). Please take the time to sign the log and to replace it where you found it. Be smart, and don't let it be as physically difficult as it looks.
You are looking for a bison tube and a figurine of Weasly himself.
