I remember watching this British comedy horror web series for the first time in July 2013 and I was twenty-three years old in that year. I thought I never saw any web series like that before in my entire life. It's kinda very dark, bizarre and disturbing but it's also very funny and entertaining. I absolutely love the series. It appears to be a dark version of an American children's television programme Sesame Street.
It's definitely not for kids as it seems to be way too frightening for kids as we know.
Anyway Red Guy is my favourite character in the series and my favourite teachers in the series are Tony, Colin and Sketchbook as well.
