It's no secret that Muppet babies became so popular, there have been multiple copy cat series based on the "Babification" genre. Some okay, some terrible, some didn't even make it out of the door outside of merchandising. (Note, I feel this thread should go in this portion, since it is directly relate, but if it needs to be moved, it needs to be moved). Hanna Barbera seemed to be the first group to get into the act. Up first, the Flintstone Kids, loosely based around the original sitcom premis, though it seems to follw the "the Flintstone Comedy Show" segmented skits route. Amoung the most memorable moments, a segment called Captain Caveman and son (following in the footsteps of shows where classic characters begat little kids for no apparent reason) Then came "A Pup named Scooby Doo"- which followed the original ideal of the series (the solving mysteries about various crooks disguising as Ghosts). A step back to their original roots after "The 13 Ghosts of Scooby Doo". And finally, Yo Yogi, considered to be the biggest failure of the lot. Yogi's Gang was now preteen, and hung around a Mall food court. A lot of classic characters like Snagglepuss and Dick Dasdarly joined them (as tweens), but the show was almost dedicated to cloning the success of Bart Simpson's personality at that point. Warner Bros got into the act twice. The first attempt was Tiny Toons. Not quite the same, as it was more of a new generation series (the original Looney Tunes appeared as teachers, and were in most of the episodes). While fans of the original Looney Tunes were critical, younger fans latched onto the show happily. Some characters took on the personalities of their elders (Plucky and Buster especially), some were insipred by their predicessors in spirit (Montana Max and Hampton for example). This show was a screaching success that lead to more Amblin co-produced series, like Animaniacs and Pinky and the Brian. The next attempt wasn't so successful. Baby Looney Tunes was almost an entire ripoff of the series, featuring Granny as Nanny. Taz was almost identical to Baby Animal. While some of the other characters retained a close approximation of their original personality, lost was the crazy chase aspect of the original shorts. This lasted only one season. The merchandise was a bigger success, and featured more characters than used on the series (Baby Road Runner and Baby Coyote appeared only on bottles and bibs) Disney stepped up to plate with Disney babies merchandise. A series was looked into, but thankfully didn't materialize. To this day, merchandising of Baby Mickey, Baby Pooh, and Baby Princesses still appears. It was not long before other, independantly run cartoon series had baby versions, most were merchandising only- Baby Garfield, baby Snoopy (short lived, as it appeared just before Schulz's passing), and Baby Popeye. Baby Felix soon popped up in Japan, as an original series. The series borrowed more closely from their own Doraemon (a double back, as Felix's bag of tricks influenced, directly or indirectly, Doraemon's gadget filled fourth dimensional pocket). I've only seen one episode, and it featured Felix being able to travle into the future to see his adult self, via the magic bag of tricks (Doraemon is able to travel freely to different time periods via a hidden time machine in a desk drawer). And finally, there's Sesame Beginnings. A DTV series featuring the Sesame characters as children interacting with their parents (or guardians). unlike Muppet babies, these characters were presented as puppets in their own series. Another dissimilarity is the appearance of Sesame Babies merchandise years before Sesame Beginings was established. If I'm missing any, please fill me in.
