Drobny the pet duck, which Lisa received from her uncle in Hungary, is lonesome. He annoys Oliver by playing his phonograph and dancing while Oliver is trying to do his taxes. Lisa sets out to perk up Drobny's loneliness by inviting Arnold the pig over to play. But alas the language barrier is to great to overcome. Drobny speaks only Hungarian, while Arnold speaks English, French, Spanish, and a little Japanese. Lisa decides Drobny needs a girlfriend and they set out to secure one for him. Mr. Haney tries to sell Gertrude the female duck, to the Douglases for $600. When that fails, he accepts the $20 that Oliver offers. Drobny & Gertrude hit it off so well, they are expectant parents soon. But of their 3 offspring, 2 are ducklings and 1 is a baby chick. (thetvdb.com)
