They Let Him Keep The Spinach.

Jack Mercer passed away in 1984 and Maurice LaMarche (Egon Spengler's voice in "The Real Ghostbusters") took over as Popeye's voice in "Popeye and Son".

For the "All New Popeye Hour" series:
Mercer played Popeye and Poopdeck Pappy...as he did since the 1930s Max Fleischer shorts to the 1940-1950s Famous/Paramount Studios shorts to the 1960s Kings Features tv shorts to the 1972 "Man Who Hated Laughter" pilot movie.

Marilyn Schreffler (Brenda the Teen Angel in "Captain Caveman", Daisy Mayhem in "Laff-A-Lympics") played Olive Oyl, The Sea Hag, Swee' Pea, and Popeye's nephews
Allen Melvin played Bluto,
Ginny McSwain played Alice The Goon (McSwain also was the voice director for the series)
and Daws Butler played Wimpy with a WC Fields-type voice imitation.

Familiar H-B regular voice actors John Stephenson, Don Messick, Hal Smith, Jean Vanderpyl, and Lennie Weinrib also played various characters (adding the prestige of finally performing in a Popeye cartoon in their list of cartoon voice credits). Stephenson played a wolf character named "Mr. No-No" during the short "Popeye Health Tips" segments in the hour show...Mr. No-No or Bluto usually did things that were bad for his health and unsuccessfully tried to get Popeye's nephews to do the same.

Jo Anne Worley of "Laugh-In" fame played Sgt. Blast in the "Private Olive Oyl" shorts.

Mercer also wrote several Hanna-Barbera Popeye story episodes.

For "Popeye and Son" LaMarche played Popeye, Melvin as Bluto and Schreffler as Olice Oyl plus
Marilyn Schreffler as Lizzie/Pugg
Josh Rodine as Popeye Jr. (Swee' Pea grown up, maybe?)
Allan Melvin as J. Wellington Wimpy
David Markus as Tank Bluto
Nancy Cartwright as Woody, Wimpy's son (Bart Simpson)
Penina (Pamela) Segall as Polly (Milhouse)
Kaleena Kiff - Dee Dee
B.J. Ward - Rad
Don Messick - Eugene the Jeep

Sadly, Marilyn Schreffler passed away in January 1988 at age 43 from liver cancer during "Popeye and Son's" one season run from Fall 1987 to Summer 1988...All 13 episodes in that series has her voice playing Olive Oyl.

The spinach-packed violence had to be eliminated per CBS network guidelines so the stories played up the competition between Popeye and Bluto and Popeye using his Spinach power to get himself and Olive Oyl out of tough situations rather than beating up Bluto...and using his pipe to toot the ending tune instead of smoking as clarified in one "Health Tip" segment. The familiar voice cast and the Hanna-Barbera sound effects and animation style made it a comfortable watch.

"Dinky Dog" had Frank Welker barking as Dinky, Frank (Yeeeeessssss?) Nelson as the harried Uncle Dudley who suffered the brunt of the slapstick mishaps that big Dinky caused., Jackie Joseph (Melody on "Josie and the Pussycats") as ditzy Sandy, and Julie Bennett (Cindy Bear) as sensible Monica. Funny slapstick. Popeye had a cameo appearance on a tv set in one Dinky Dog episode

The complete 32 10-minute episode (16 half hours) "Dinky Dog" series (no references to Popeye in the opening and end credits) was released on DVD by Canadian firm VEI instead of Time-Warner since Hanna-Barbera's "Popeye" and "Dinky Dog" were animated by Hanna-Barbera's Australia Pty Ltd studios (Southern Star).

Some H-B Popeye cartoons were released on home video and DVD under license by King Features Syndicate

As emeraldisle noted, they were from the 1960s "King Features Syndicate" cartoons usually directed by Jack Kinney, Gene Deitch, Larry Harmon, William L. Snyder, or Seymour Kneitel/Paramount Studios...the opening and closing had the King Features logo with a horse rider carrying a big feather plume writing instrument...the plume moved on its own and usually wrote a cursive "The End" at the end of the cartoon. "Krazy Kat", "Beetle Bailey", and "Snuffy Smith & Barney Google" cartoons from that era were also produced by King Features Syndicate.

The Professor's name was Professor O.G. Whottasnozzle, originally created by Elsie Segar for his "Thimble Theatre"/"Popeye" comic strip.

The Hanna-Barbera and 1960s King Features cartoons featured appearances by Sea Hag, Eugene the Jeep, and Geezil from the Segar comic strip but Professor Whottasnozzle and Rough House the diner cook only appeared in the King Features cartoons.

I had never yet experienced Hanna Barbera's continuations of the Popeye franchise. My memories of Popeye the sailor man came from Cartoon Network. So i watched Popeye on "The Popeye Show" and "Late Night Black and White" and those were usually on in the very late hours of the morning. But i only recall CN ever airing the 30s to 60s ones on there.

I enjoy Popeye but i admittedly haven't bought any of his dvd sets. But it's on my mind. I would also check out the HB ones too if that day comes. Which i assume could as long as WB retains that Popeye on DVD license.

Dinky Dog was one that i also clearly never saw due to it not being retained. So when it came out to DVD, i blind bought it and i admit i was pleasantly surprised. Dinky is hilarious. I really enjoy his bungling and his "bow-wow-wowwie". In a way i'm sad this was it for this character. I would have digged him coming back in group shows but i suspect it was not meant to be.

Also of note, for what is more a sitcom classified show, Dinky ends up getting to discover a lot more monsters and similar stories more akin to scooby's 80s supernatural adventures. It seems like Dinky was just an oddity. It even received a concept change in the second season.

Also friendly note: VEI has seemingly got a new trick when it comes to older releases. If you are waiting to buy this one or Drak Pack. Watch Amazon's third party lists. Since when VEI makes new ones they upload them there on their official account. And when they do they are the cheapest you'd find. A lot of stockpilers and scalpers will typically buy them up to relist for higher prices and may have you waiting several months before VEI does it again. Notice how Dinky Dog's third party page looks now with an official VEI link and how Drak Pack looks since the last VEI link they had on that one sold out.

The clock episodes were from the 1960-era Popeyes commissioned and farmed out by King Features Syndicate to many producers, in this case the majority, not one of the regulars, the holdover Famous
but Jack Kinney (using the Jay Ward sound effects!) "Dinky Dog" was rather fun...
