 In this episode, Eddie faces one of life s mysteries: Is there really such a thing as a "green thumb"? None of his classmates seem to be having any trouble growing sunflowers for Miss Toliver s study of variables. Btt, day after day, all he sees when he looks into his little pot of soil is...soil. Eddie tries everything he can think of, and gets more than enough advice from friends Vincent and Johny, his building superintendent, Fred (Danny Dennis) and his Aunt Rosa. Even the pros chip in, with insights from the leaders of New York s Green Guerilla rooftop gardeners, and the manager of a huge rice farm (Lundberg Farms) in the broad, flat fields of rural northern California. But all to no avail. Eddie starts to think that as far as green thumbs go, either you have one or you don t---and he doesn t. But after a chance encounter with someone he knows very well, but has never met (NY radio personality Glenda) (Penelope Crabtree), Eddie digs up an answer.
