Daws Butler & Janet Waldo in The Space Kiddets (1966)

This Hanna Barbera series set in space features a gang of kids who were constantly beset upon by space pirate Captain Skyhook and his evil henchman Static (both Butler). The kids were less distinct, though they did have cute names, including one named, oddly enough, Snoopy. Their dog was called Pupstar. The shows were originally produced as 15 minute stories meant to be interspersed with other content in a half hour time slot.

The clip above is the opening sequence, uploaded by cartoonboy180. One of the more memorable conceits of the show revolved around a treasure map that the Captain wanted from the kids, but was unwilling to do them harm to get. Static on the other hand was more than willing to go that extra mile and was constantly being kept in check by the Captain, as can be seen in the clip below, uploaded by WarnerBrosOnline. The animation style was clever and sophisticated with something of a Chuck Jones quality to it, as evidenced by the quivering spaceship in this clip.

This series has made it to DVD, along with the show that replaced it - Young Samson. It's part of the Warner Archive collection.
