The Case of the Missing - S1-E1
Revealing mistake: WPC Softly leans on a model building in Rammel's office, causing it to collapse by stages. The wire that is being pulled to make the model collapse can be seen to the right of the model. (00:21:00)
Continuity mistake: Tony Sparkle is seen defacing a picture of Judy Talent. He starts writing something beginning with T. The action cuts away for a moment, and then back again. The words on the picture are "SAD OLD BAT". (00:07:05)
