She was sweeping the floor of the auditorium where the Space Ape was first sighted.

After the alien attacked Captain Treesdale in the kitchen, she rushed in to investigate. She noticed that he needed medical attention, as he was wounded by the alien and had developed a rash. Then she ripped apart a piece of cloth and created a sling for the captain's arm. She managed to carry out of the kitchen to the infirmary.

When the gang ran into Elliott Blender, Elliott said that he found something interesting in Celia's closet. Inside was a series of hi-tech gadget. The gang then started to suspect Celia to be the Space Ape.

After investigating Keith Dale, Mystery Inc. saw Celia leaving the tank room. They went inside and noticed that she attached something to the security camera. Fred retrieved it and identified it as a radio transmitter.

After Janet Lawrence was revealed to have been the Space Ape, she managed to disable the policemen restraining her. Celia tripped her as she tried to escape. There she revealed herself to be an FBI agent sent to investigate possible alien activity. While she acknowledged that the Space Ape was a fake, she stated that somewhere aliens were waiting to make contact.
