When Oakley senses an unusual tingling in his leaves, he remembers that today is a very special day - his birthday. The only problem is, Oakley doesn't know how old he is! Rosie and her friends decide to arrange a surprise party that Oakley will never forget - but first they need to do some investigating. They discover that only one other tree knows the truth - the Grand Old Oak who lives far away in the east. With friendship on their side and a set of magical clues and a compass to guide them, Rosie and her fellow explorers set out on an exciting adventure to find out Oakley's age.
