The Bash Street Kids has had a number of spin-offs, including Pup Parade, Simply Smiffy, Plug and Singled Out.
The Dandy has had two similar series: the 1970s Whacko (about a teacher who taught in a suit of armour because of his unruly pupils) and P5 from 1998 to 2000, also about a class and their long-suffering teacher.
