Animation
Popeye and Olive enter the city of Badgag and spot Bluto doing magic tricks. He hypnotizes Olive like a snake charmer. Bluto introduces himself as the Great Bourgeois and gives Olive a fancy dress, turns Popeye into a donkey, and sits on a bed of nails. Popeye pounces on the bed and turns it into springs. The boys next compete in snake charming; Popeye blows a hornpipe on his pipe. Bluto next turns Popeye into a parrot. Bluto then locks Olive in a basket and does the sword trick; Olive escapes and gives parrot Popeye his spinach, which revives him. Bluto escapes with the rope trick and a flying carpet, but Popeye uses his pipe like a rocket to get aloft. Another battle, with Popeye using Bluto's own magic to turn Bluto into a canary. Popeye and Olive fly the carpet home, past the Statue of Liberty.
Animation
Olive is building a house when the boys happen by. They show off a bit to convince her to let them build her house for her. She decides to split the job in half by splitting the blueprints in half and having each build one side of the house. Of course, "cooperation" isn't in their vocabulary. Bluto does an extremely sloppy job on his half, and also takes every opportunity to either sabotage Popeye or trick him into doing more work. Meanwhile, Popeye's making enough of his own mistakes, many of which seem to involve wedging Olive into small bent pipes. Eventually, Popeye has his spinach and finishes the house, but the house collapses as they are celebrating with a kiss.
