The Squirrels have just got some new walkie-talkies and are having so much fun with them. Duggee calls the Squirrels to come for some blueberry juice, but as Tag is running, he trips over a car and falls through a secret door in the wall! Communicating through his walkie-talkie, Tag doesn't know where he is. He can see lots and lots of things around him, but no-one has any idea where this room is in the house. As Duggee listens to Tag describe what's in the room, he realises that Tag must be in the lost property room. But Duggee doesn't know where in the house that is. He's going to need to go find the map of the house which he has hidden somewhere. Whilst Tag explores all the treasures of the lost property room, the Squirrels search for hints to where the map could be around the Clubhouse. Finally, after looking all over the house, Betty finds the code on a piece of paper, opens the safe and gets the map. Tag has been entertaining himself dancing with a lion statue and playing a church organ. Duggee still can't remember where the lost property room is, so Tag gives him some tips for remembering where you might have left something when you lost it. Take a deep breath, think of where you were last time you had it and.... boom! Duggee remembers he put wallpaper over the lost property room door! The Squirrels and Duggee find where the door is and enter into a room filled with stuff - and also Tag!
