Scooby-Doo Solves It with S.T.E.M.[]
He made an unexpected appearance at the entrance to the cafeteria, where he frightens away everybody with an ominous message about tonights school dance being cursed and they'll be doomed forever if they stayed, before tearing down the banner and disappearing down the hallway.
He broke into Professor Curie's chemistry class and smashed the place up, breaking beakers and spilling salt on the ground, and then stole some bottles of hydrogen peroxide.
He gotten the gang's attention after zooming down a hallway to the gym and caused the ticket table to be rusted with the salt and hydrogen peroxide.
A spare costume of the ghost was found in the hall leading to the chemistry class, which made the gang suspect Curie, but she was proven innocent as it was too small for her to wear.
The gang settled a trap up at the tonight's dance, thanks to the help of Professor Curie. Using their own chemical reaction of water and soap to make the ghost slide into a net setted up on stage.
Brian unmasked.
The ghost was trapped and revealed to be Brian, a student at the school the gang went to. Earlier that day, he wanted to ask Velma if she could go to the dance with him, but she replied saying no as she was busy. This of course gotten him mad and conducted the scheme of dressing up as a ghost and using chemical reactions to scare away the students from going to the dance, since he thought if he couldn't go with someone, then no one else would.
