Tops in the Big Top is the 133rd Popeye cartoon, released by Famous Studios on March 16, 1945. It features Popeye as a lion tamer, trapeze artist, and protagonist; Olive Oyl as Popeye's assistant and love interest; and Bluto as ringmaster, strongman, acrobat, and main antagonist.
The cartoon begins with an outside view of a huge circus tent with banners flying. We are led inside, where we see Ringmaster Bluto in a spotlight introducing "that death-defying sensation, Popeye!". As Popeye begins to put his head inside a lion's mouth, Bluto morphs momentarily into a wolf and, fingering his mustache, muses, "Hmmm, what a feature attraction I'd make with Olive Oyl!" He sneaks a raw steak on top of Popeye's head, which makes the sailor a laughing stock with the crowd and leads to Olive's accusation that he is "butchering the act".
Next we see Popeye on the high-wire, blindfolded, holding an upright piano on which Olive plays "Ac-Cent-Tchu-Ate the Positive". Bluto eats a banana and tosses the skin right beneath Popeye's foot. Popeye slips, and suddenly the pair and the piano are being held aloft by the tenuous hold of Olive's nose on the wire as the crowd howls in derision. To make matters worse, Popeye hyperventilates, and the effect on his pipe gives Olive a hot foot and sends the whole act careening to Earth. Bluto then sabotages the safety net, knocks Popeye out cold, and pours a bottle of whiskey over him to make him appear inebriated. Olive sniffs him and screams: "He's DRUNK!!" as the crowd boos. Bluto grabs Olive in an embrace as he proclaims, "Babe, the show will go on!" He rips off his ringmaster's outfit to reveal an acrobat's leotard, and he flexes his muscles as triumphant music blares, the crowd roars its approval, and Olive tells Bluto he is handsome. The large fellow picks up The Sailorman and tosses him out of the ring with a derisive order to "Hit the road, ya bum!"In the next scene, we see Bluto hanging from a trapeze bar by his feet, utilizing Olive Oyl as a yo-yo, kissing her on every rebound as she screams for Popeye. At last Popeye finds his way to his spinach and pops himself into Olive's tutu and takes her place at the end of Bluto's yo-yo string. As Bluto kisses Popeye, Popeye pulls the big guy off his perch by his beard and a fight ensues on the trapeze high above the crowd. In the final exchange, Bluto misses with a left hook but Popeye nails him decisively with a right. Bluto sails the width of the great circus tent and through a series of impediments and right into a 'human cannonball' cannon. Popeye pulls the fuse and we watch the devastated bully get catapulted from prop to prop in the upper reaches of the tent.
Popeye makes a mock attempt to "rescue" Bluto with a high dive tank from which the bottom is missing. At the last moment he substitutes a water bottle from a drinking fountain, and as the scene closes we see Bluto bottled up helplessly and held aloft by a victorious Popeye as mocking music plays.
