History[]
Scooby-Doo! World of Mystery[]
She arrived at the Eiffel Tower and introduced herself to Monsieur Bonnet, the owner of a cafe who was giving the gang a task to help take care of a ghost sighted floating around the tower, she explains that she can talk to spirits which was enough for Bonnet to allow her to help out. Despite the rest of the gang thinking she's a bit weird.
She surprisingly had a head start before the gang's arrival and used her mind reading to sense a poor individual, and that everyone needs to check higher up, which Fred thinks she's just faking it all, but Velma understood that she was remembering a past event involving a woman getting pushed of the Eiffel Tower by a young man after a refusal for marriage. She later used her mind reading ability again to sense the ghosts presence getting stronger another floor above.
Her mind reading soon came to an end after the gang trapped the actual ghost, which was actually a parade balloon that got swept away from heavy winds, and she felt sad after discovering the truth, wishing the spirit to rest peacefully. The gang soon left her thinking she was acting crazy and returned the balloon to Bonnet.
