The firm has picked up the EMEA licensing rights (excluding Spain and Portugal) to the series, co-produced by master toy licensee, Bandai, which is aimed at three to six year-olds.
Jelly Jamm is set on a magical planet called Jambo, the origin of all music in the universe.
It follows the adventures of five friends who live on Jambo and the fun times they have with music and dance. Bello and his friends Rita, Goomo, Mina and Ongo learn to express themselves through music.
Co-produced by Spanish indies Vodka Capital, Secuoyas and TVE (TV Espania), the series is the latest creation from Pocoyo creator and director David Cantolla.
Turner Broadcasting has acquired the 52 episodes of the series, which it plans to air on Boomerang in over 130 countries.
Alan Fenwick, vice president, Turner CN Enterprises, said: "When we relaunched the business as Turner CN Enterprises back in 2008 we clearly stated our ambition to develop our business beyond our core boys brand expertise.
"The pre-school sector is an integral part of this strategy but we’ve taken our time to find the perfect brand to mark our entry into this market. Jelly Jamm has all the key attributes of a highly commercial property and I’m sure that it will make its mark in this highly competitive sector when it launches at retail."
