This is the first Speedy Gonzales cartoon featuring Daffy Duck as an antagonist. Daffy would become Speedy's co-star in 25 other cartoons.
Final Daffy Duck cartoon directed by Friz Freleng, and the only cartoon that he directed in the DePatie-Freleng era.
First appearance of Daffy Duck, and the one of the two appearances of Granny in the DePatie-Freleng era.
Daffy, Sylvester, Granny, but no Tweety. Instead, there's Speedy Gonzales. And Granny appears to be using Silk n' Silver hair rinse, as she's gone a few shades darker.
This is three of the four cartoons that Sylvester appeared in the DFE era.
