The Adventures of Holly and Callahan is an animated television series based on the Angry Birds game, Angry Birds: Out of Darkness, created by Rovio and Nevrade Entertainment. The series chronicles the adventures that Callahan and Holly cause after the events of Angry Birds: Out of Darkness. It was first teased on Angry Birds' social media accounts and on Angry Birds' Youtube channel.


The show takes place on a small island called All Terra. The main events of the show take place near Holly and Callahan's houses located in a small forest. The surrounding area is covered in Pig Cities and rolling hills. During the events of the series, many buildings are being constructed.


The series mainly focuses on two main characters, Holly and Callahan, but the series often diverts the focus to other characters.

Callahan is an energetic joke loving person with almost no worry. Callahan has been shown to care for his friends, and risks his life to save them.

Holly is a shy timid person who really only fights if necessary, and prefers to talk things out. She tries to be kind, but sometimes she overdoes it.



  • Bubbles the Amoeba, and Callahan's Old Shipmates are two episodes that have concepts.
