Animation mistakes and/or technical glitches

  • After the Moving Mollusk is launched off the turnstile on to the train and it leaves, the second track, the other subway platform, and the city backdrop are all missing.
  • When Lester Leonard is shown appearing to catch the Mollusk, Scooby and the gang are positioned inconsistently from the background. They are undersized and appear to be floating above the ground.

Inconsistencies/continuity errors and/or goofs/oddities
