Plot

Bimbo and Koko are among the contestants in a big auto race, where all the talking animals in Fleischer-land are in attendance. The favorite in the race is Betty Boop, but she's late again, and her Yiddish-accented car has no idea where she is. When Betty finally shows up, she explains in song that her tardiness is due to a "'code' in my 'doze'".
Once the race begins, it's a real thriller-spiller, with even the spectators getting into the act—and catching Betty's cold in the process " Eventually, Betty wins the race.
