"Lumpy Joins In" is the second segment of the thirtieth episode of My Friends Tigger & Pooh.
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.
