The animation presents Dr. Bermuda Schwartz's silent explosive as "Hush-A-Bomb", but it is repeatedly called "Hush-A-Boom" in the dialogue.
The grumbling potter's shop has the word "POTTER" prominently above the door, a light-colored facade with darker, turreted buildings on either side. In one scene, he is shown going from his shop to his home. As he passes along the street, his shop marked "POTTER" is seen three times in the background. (This is the result of the show's 'minimal' animation techniques, in which a drawing of a forest or city or landscape background is repeated as the main action moves in front of it.)
