I just stumbled on Pee-Wee Herman and the Alien Invasion, a very short super-8 film shot by an 8 year old (back in the 80s, I assume). Pretty well done, considering. The claymation part works nicely. It’s not all that exciting, I guess, but it made me smile anyway.
You can compare it to Pee Wee’s Brain, which was an actual clip from Pee Wee’s Playhouse, also with claymation.
