The 52x5mins Toggle will launch on CBeebies in 2015.
The show is billed as an “an inventive, unique and fun series with a bright eye-catching design”. It follows a trio of young, creative creatures that live and play in a big forest. They create characters by combining colourful shapes to solve problems they encounter.
Children’s author and Charlie and Lola animator Leigh Hodgkinson and BAFTA-winning toon creator Steve Smith, who runs Beakus (Numtums), conceived the series.
Fonic, the sound design team behind successful kids’ series such as Peppa Pig and Mike the Knight is also attached.
Union, which former HIT Entertainment and LazyTown sales boss Selly launched last year, has secured international distribution rights.
“I am very happy to be adding this beautiful and original new show to our growing roster of high quality new animation series. I am sure it is going to prove to be a huge success around the world,” he said.
