When Belinda Bear, a circus trapeze artist, loses her good luck tiara, it?s up to Huckle, Lowly and Sally to find it. The Mystery is on then off then on again as they keep seeing Belinda with her tiara then without it, with it, then without it. It?s only when Huckle realizes Belinda has a twin sister Maxine that they?re able to solve the mystery. Mr. Frumble has lost a prized butterfly stamp from his collection. Thinking that he may have accidentally mailed it away on a birthday card, Huckle and his team chase the envelope all the way to the post office...but the stamp isn't there. It turns out that the stamp was stuck to a teacup all along.
