The Pink Panther motor scooters down to "Biceps Beach (in reality - it's Venice Beach near Los Angeles in the late '60s where all the bodybuilders would hang out and lift weights, get a tan, pose and just hang out with friends.)
In here, the first muscle man is a real vanity case, posing in front of a group of admiring females, trying to impress them. The PP puts on his sweatshirt and inflates it to where instantly he is Arnold Schwarzenegger. Our hero even has inflatable barbells!!
The rest of the story is a demonstrated of the amazing inflatable objects the Pink Panther has in his satchel. He can produce anything and some of it winds up some real, some are just blowup objects. It's the usual bizarre visuals and the Panther and Mr. Muscles duel it out.
There are so many jokes in five minutes here you can't have all winners but mostly it's clever and fun to watch, most of the gags successful. The best stuff, I thought, was in the beginning leading up to the Panther's surfing exploits. In all, typical PP lunacy.
