During a Cinco de Mayo fiesta, Speedy Gonzales is in a big Peeng-Pong exhibition. He is so fast, he is the only player as he is able to race across the table before the ball gets there to hit it back. A mouse in the audience says Speedy goes steady his sister, then another says that Speedy goes steady with everybody's sister. A fat bird flying overhead exclaims "Mouseburgers!" and swoops down as the audience scatters. Speedy tells them not to worry; he'll take care of Señor Vulturo.
The bird swoops down on a mouse, but Speedy pulls him out of harm's way and sticks a lit firecracker in the bird's talons. He soaks his hot foot in a rain barrel, but Speedy scares him and he falls in. He asks Speedy why he stole his supper and tries to swat him, but the mouse just sings and dances away. The vulture chases him out of town, but Speedy makes him stop on the railroad tracks and a train clobbers him.
Señor Vulturo aims a cannon at Speedy, but the mouse races behind him and scares him again. The bird leaps in the air and comes down in front of the cannon, just as it explodes. Speedy says he'll never catch him, but he promises to show the bird the way to a big fat mouse. He leads him back to town but ducks into a mousehole so the bird smashes his head against the wall.
To get back at him for lying, Señor Vulturo gets a ball-and-cup game, fills the cup with nitroglycerin, and presents it to Speedy. Speedy likes playing with it, but never tries to get the ball in the cup. The bird gets mad and shows him the real way to play, and blows himself up.
Señor Vulturo calls a truce with Speedy. However the rodent puts him in a tent at the fiesta, where customers can throw balls at his head and darts at a target on his behind.
