Notes/trivia

 * When Scooby laughs after Shaggy uses the kit on Velma's hand instead of the doorknob of the Kingston Mausoleum, the door itself is missing
 * The fact that Velma brings out the finger printing kit out of nowhere could be toon physics. Also, using one looks quite professional of them, but the fact that they only use it this one time when they could've used at any time it would've been useful (which is most of the time), it just looks too convenient. Although perhaps using only once was intentional as it probably would be less fun to keep relying on it even if it does look odd only using it once.
