First of all, being strapped to a cactus, and later running with a cactus piggy backing on you defies all logic even if it is a cartoon.
Considering that Hanna-Barbera was behind
The Flintstones, it's no surprise that the teenage Pebbles bears a striking resemblance to Daphne of the
Scooby Doo series amongst some other female characters of the Hanna-Barbera franchise.
But in terms of the clip, how old was Bamm Bamm supposed to be in the spin off? With his voice cracking, I assumed he was at least thirteen, the blissful time for guys to hit puberty. But the way he was depicted, he looked like he was in his mid-teens.
