The makers of Angry Birds are launching a cartoon series this weekend, expanding further beyond its highly addictive games in a bid to expand entertainment and merchandizing.

Rovio Entertainment Ltd, based in Espoo, Finland, is the company behind the popular mobile app game Angry Birds. The company said the cartoons will feature adventures of birds that appear in its games.

Episodes of the series Angry Birds Toons can be downloaded through on-demand services.

The cartoons will also air on television channels such as FOX8 in Australia, ANTV in Indonesia, Cartoon Network in India, and MTV3 Juniori and MTV3 in Finland, it said.

Rovio has expanded into merchandizing and licensing in the past few years and its colorful, round bird characters are sold as stuffed animals and appear on everything from T-shirts to soda cans.

The company announced in December that it hired Hollywood executive David Maisel as executive producer of a 3D animated film planned for release in 2016.
