The first series aired in 2015 premiering on the BBC channel CBeebies, followed by the second in 2018, and the third in 2022.

Development
The concept was picked up by London-based CG studio Squint/Opera. Working with Squint/Opera the concept was developed and re-imagined as a 52 part children's show combining live action footage with 3D renderings of Messy, his friends and the world of OKIDO.

The show aims to tackle a scientific topic in each episode, beginning with a question posed by Messy, for example: why do some things float and some things sink? He travels to OKIDO to discover the answers with the help of his friends Zoe & Felix and science trio Zim, Zam & Zoom who all have specific abilities which help them in their adventures.

Messy
Messy (Adam Buxton) is a blue monster, excitable and curious. He lives underneath a bed and ventures out often to discover new things and learn. Whilst Messy means well his excitement can often land him in trouble, he can't control his urge to push buttons and can never get enough of eating socks (green socks are his preferred snack) and sandwiches. Whenever Messy finds something new that he's curious about, he travels to OKIDO to meet his friends and discover the answer.

Zoe
Zoe (Kate Harbour) is one of Messy's best friends who lives in OKIDO with her brother Felix. Zoe is very smart and sensible, she hates being late and getting lost but has a passion for gadgets and gizmos, her favourite is her communications watch which she can use to call Zim, Zam & Zoom.

Felix
Felix (Shelley Longworth) is one of Messy's best friends who lives in OKIDO with his sister Zoe. Felix loves using his imagination, being inventive and being prepared. He always packs a rucksack with useful things to help on their adventures.

Zim
Zim (Rob Rackstraw) is a yellow talking computer with a white screen who knows a lot about science. He works in the ZZZ Tower with Zam and Zoom. Zim is not very good at practical things like reading maps and this often leads to disagreements with Zam. Whenever Zim gets confused his screen starts buffering.

Zam
Zam (Kate Harbour) is a triangle-shaped engineer who is brilliant at fixing things; she also works in the ZZZ Tower. She is quite bossy and sometimes tells Zim off if he is getting in the way. Zam uses her tools to make all kinds of gadgets and vehicles. Zam also loves doing experiments, particularly when they blow up.

Zoom
Zoom is Zim and Zam's lab assistant. Zoom can morph into any shape he wants as long as it is not bigger than his body. This is very useful when the OKIDO gang are on an adventure. He doesn't speak but can make noises. Zoom is the only character, aside from Messy, to appear in every episode.
