Continuity mistake: While Fred and Barney are fighting, when Pebbles and Bamm-Bamm are devising a plan together in baby-talk, the black strap is over Bamm-Bamm's left shoulder, but when Bamm-Bamm walks past Fred and Barney the strap is over Bamm-Bamm's right shoulder. (00:22:55)
Continuity mistake: While Fred and Barney are being chased by the police, in the closeup of the stop/go signal we see two ropes beside the monkey's hand - one controlling "stop" and one for "go", but in the wideshot there's only one rope hanging from the post, apparently controlling both "stop" and "go" signals.

Continuity mistake: During the hearing, when Perry Masonry is questioning his client about being fixed financially, part of Perry's string loop closure on his clothing vanishes within the same shot, and then reappears. A few moments later Perry's two parallel strings are crisscrossed, then both are back to normal. Later, when Barney asks Perry if he can hold Bamm-Bamm, once again Perry's parallel strings become crisscrossed. (00:20:35)
Continuity mistake: After Fred and Barney leave for the hospital without Wilma they realise the mistake and head back to the house, and when it cuts to Wilma in the bedroom Dino jumps atop the blue blanket on the bed, but in the next shot the blue blanket is gone, and then it reappears for Dino to hide under.

Continuity mistake: When Fred is trying to work out what kind of talent Pebbles has, she has her bathing suit on. When Pebbles is seen crawling onto the stage when it's her turn, she has her regular clothes on, and when Pebbles is on the stage with Dino, she has her bathing suit on again.
