Blackboard

Blackboard is a talking blackboard with a face that looks like a gargoyle. It is found in the Detention Dimension where Cloud Tower students are sent for misbehavior.

Appearance
It has a purple face that resembles a gargoyle's with sharp teeth and black eyes with red pupils and a body for writing like normal blackboard.

Personality
It is very obedient as it tells the Trix to follow what Headmistress Griffin had told them. But it also appears to be very naive as it can be fooled easily by Darcy's trick.

Season 3
In "Fury", The Trix were sent to the Blackboard by Headmistress Griffin, where they had to write 600 ingredients that could be used in a mayhem potion.
