Sherlock's Andrew Scott takes on monsters for CBeebies
The animated pre-school series, School of Roars, is about five young monsters as they experience school for the first time.
The five monster-lings tackle each school day with the help of their lovable teacher Miss Grizzlesniff, voiced by Kathy Burke, who guides them through monstery classes in maths, music, cookery and life.
Sarah Lancashire appears as the Headmonstress, Mrs Twirlyhorn, and Sherlock villain Andrew Scott, plays the narrator – as well as a number of other characters including Mr Marrow the cookery teacher.
