The Jobberknoll was first introduced by Professor Riddoc in Care of Magical Creatures class during Term 8. The creature later made its reoccurence in the classroom. They are silent creatures up until the moment of their death, when they emit a long cry made up of every sound it ever heard in its lifetime backwards.
The Jobberknoll is described as a tiny blue-speckled bird with their diet consisting mainly of small insects. Their feathers are useful, harvested in Truth Serums and Memory Potions.
