Paku-Paku Mama (Patreon)

Paku-Paku is a Japanese ideophonic term for eating hungrily, and is the "Pac" in Pac-Man. "Paku-Paku Mama" was a cute and famous Showa Pop song from the 70s. 

A parody version (with overhauled lyrics) is the ending song for the anime Okaasan Online. When I first heard it I ROFL and was like, "WHO'S your target demographic here? People like me who grew up watching Captain Harlock and Gatchaman/BOTP?"
