Adventure runs in Poppy Pepperton's family! At the age of ten, Poppy is the greatest explorer since her grandfather Pappy Pepperton, travelling the globe with her trusty sidekick/legal guardian Colt Winchester. When a shrunken mummy head gives a series of clues to discover an exotic fish no one's seen in years, adventure calls, and Poppy and Colt find themselves in the strange city of Old Macadamia, swimming alongside the gigantipus, trailed by a strange robot - and end up uncovering clues to the greater mystery of what happened to Pappy all those years ago!
