Humphrey'S Tiny Tales 5: My Treasure Hunt Trouble!
"I was unsqueakably excited when Garth took Og the frog and me home for the weekend, because he was having a birthday party! I was expecting to have a GREAT-GREAT-GREAT time. I wasn't expecting there to be a thief, hidden treasure, and a mystery only I could solve!". This is a specially extended version of Humphry's 2011 World Book Day Book.
