Hey Duggee

Hey Duggee is a British animated educational preschool television series aimed at two to five year olds. Created by Grant Orchard, it is produced by Studio AKA, in association with BBC Studios (formerly BBC Worldwide). The show is narrated by Alexander Armstrong.
The programme is based around The Squirrel Club, an activity club for children. The children take part in all kinds of activities, have adventures and earn badges for their accomplishments. Each episode shows the squirrels complete an activity or adventure relating to a badge, that the squirrels earn at the end of the episodes. There is no set formula for every episode, with many episodes referencing or parodying pop culture.
"Hey Duggee" has three series. It was first shown in December 2014. BBC and Studio AKA produced a second series in early 2016, with the first episode airing in the United Kingdom on 26 September 2016. A third series was commissioned in October 2017, with the first episode due to be broadcast in Autumn 2018, but was pushed back to 4 March 2019. It aired until September 2021 with a Christmas episode shown in December 2020. The third series received increased acclaim and popularity amongst children and adults alike during the 2020 pandemic lockdowns. It has been renewed for a fourth series.
In the United States, the series airs on Nick Jr. on 11 July 2016.
Production.
The programme is animated using the computer program Flash, with a minimalist style using filled shapes with no outlines, and only effects that Flash is capable of, and only the Duggee character regularly uses gradients. For example, if there is a frog character, then it usually bears the appearance of a plain green triangle.
The production team consists of around 16 in-house animators, with six to eight scriptwriters.
