Popeye is building a house while his nephews practice music. The nephews try to help him but end up causing trouble, so Popeye sends them back to practice. After Popeye finishes the house and goes inside, it collapses. The nephews then decide they’ll help build and practice music at the same time — they build a skyscraper luxury apartment in musical style (to the tune of the "Poet and Peasant Overture") while practicing.
