Jabberjaw was set 100 years into the future, and the titular shark (Frank Welker) was a domesticated drummer for a rock band. The Neptunes, who probably can't use that name for a revival due to the real-life group fronted by Pharrell Williams, unless he's a fan of Jabberjaw, were a futuristic analogue for Josie & The Pussycats, the Archie comics band that H-B had a license for a few years earlier.
In the series opener, "Dr. Lo Has Got to Go", the gang takes on the titular mad scientist (Keye Luke) and his size changing dragon......
Wouldn't be at all surprised if Ruby & Spears also developed CBS' Clue Club, the other H-B freshman entry that year.
