Hidden Side Wiki
“I've heard every excuse in the book. You're going to class.”
— Mr. Clarke, to Parker

Mr. Clarke is a teacher at Newbury High School. He became possessed by Mamali and became a Gloombie.


At an unknown point in time he became a teacher at Newbury High School. He seems to be the science teacher.

Gloom and Doom

While Jack was running away from Parker, he entered a classroom where Mr. Clarke was teaching. Jack uses a skeleton to make Parker laugh, but she continues to chase Jack.

Parents Just Don't Understand

Mr. Clarke calls in Jack and Parker, as well as Rose and Parker's parents, to explain why they missed an assignment. When Rose tried to apologize for them, he replied that he doesn't accept it before revealing he had been possessed by Mamali. After glooming the parents, Mamali unpossess Mr. Clarke. He is later seen when the Davids and Jackson families leave throwing up a lot of gloom over the railing.

Haunting 101

Mr. Clarke stops Parker in the middle of the hallway and tells her to go to class. When Parker tries to explain he refuses to listen since he "heard every excuse in the book" from Parker (and Jack) and firmly tells her that she is going to class, which she reluctantly does. Later on, when Jack flicks the light switch from the Hidden Side to get Parker's attention, Mr. Clarke was rather confused but the class still continued.


He seems to be a rather stern teacher as he called in Jack and Parker's parents for missing one assignment and refuses to listen to Parker when she tries to say that she can't attend his class since "heard every excuse in the book" and made her go to class, not caring what her emergency was. However, it's possible that Jack and Parker skipped his class one too many times (because they were too busy Ghost Hunting) and that made him be severe with them.
