On August 17, 2023, Rifftrax performed their 34th Live Event riffing the 1980's BMX film "Rad". Michael J Nelson, Kevin Murphy and Bill Corbett also riffed on two Gumby "Adventures" ("The Witty Witch" and "Hidden Valley") . Rad star Bill Allen attended the event at the theater the event was broadcast from. ("Rifftrax Live: Rad", Rifftrax Event)
So yeah, this is basically an anthology of old cartoons. The framing device is nonsensical and saccharine in a way that would make Disney blush (culminating in a bizarre bit where various advertising mascots appear out of nowhere to go "thank you, George Pal" into the camera), and while the shorts themselves are technically extremely impressive, most of them are also incredibly racist, even for the time.
From the episode Dragon Daffy from Gumby.... That introduced Prickle's Mother.
Yep, Prickle's Mother bears a strong resemblance to Prickle... Except bigger, since she is an adult... Prickle is smaller because he is revealed to be a Child.
Yep, Prickle the Dinosaur is actually a little dinosaur child with child prodigy.
His mother taught him, fed him, closed him, cared for him, and protected him.
That's why whenever Prickle gets bullied, his mother comes to his rescue.
That's why Prickle and his mother loved each other. Like Mother, Like Son.
