This show really sucked. It was another horrible "Scooby-Doo" ripoff show (something Hanna-Barbera did A LOT in the 1970's), execpt instead of a Great Dane for a title character, we have a Shark (but a really lame shark at that) who is protecting a band called "The Neptunes" (They do have a bit in common to our well known sleuths on "Scooby-Doo"), and in the process, they all solve mysteries. But the worst thing about this show is how Jabberjaw uses Rodney Dangerfield's signature "No Respect!" line, and Curly Howard's signature "Nyuk-Nyuk" line. What is up with that? Why didn't Dangerfield sue? Why didn't the Howard family sue (If these were my lines, I'd be taking Hanna-Barbera to court)? I guess that's a question for another time.
Bottom line: This show sucks.
