Sponsored Weekly Tournaments

Every week in Angry Birds Friends, there is a new Weekly Tournament. Sometimes this tournament may be themed or sponsored. Sponsored tournaments often support good causes, such as the Champions for Earth tournament, which was sponsored by the Earth Day Network.

Freddie For a Day Tournament
This was the second time Rovio has supported Freddie For a Day, the first time being in 2012 with the creation of the Freddie Mercury bird as a mark of support.
 * Ran from: September 2-8, 2013

Roll with the Pangolins (Pangolin Tournament)
The tournament was endorsed by Prince William, Duke of Cambridge, who is the president of United for Wildlife. United for Wildlife work to fight illegal wildlife trade, and so did this tournament. The tournament was created to support the conservation of pangolins, the world's most endangered mammal.
 * Ran from: November 17-23, 2014
 * In support of: United for Wildlife

An original short, "Meet the Pangolin" was created to promote the tournament. Two birds (not Angry Birds) watch a pangolin eating insects and ask what species it is. The birds mishear the pangolin's answer, thinking it is a penguin and a mandolin. The pangolin breaks down its name and tells the birds to "deal with it". One of the birds says "Doesn't look like a penguin to me".
