Pooh's Cookie Tree: When a cookie falls on Pooh's head from a tree, he figures that it must be a cookie tree. Finding this a delightful idea, he calls upon the Super Sleuths to see if there's a way he can have one in his yard. Meanwhile, Lumpy and Roo find themselves facing a mystery when the cookies they were delivering to Heffalump Hollow go missing. Lumpy Joins In: Lumpy has always wanted to sing a choir, but the Heffalump choir is only for adults. He's delighted when Rabbit starts a choir and promises to include everyone. Lumpy's unique brand of singing, however, is more like trumpeting and doesn't seem to fit in with Rabbit's tune. Darby, Tigger and Pooh come together as the Super Sleuths, determined to help Lumpy find a way to join in.
