The T-Rex was a puppet dinosaur who was a side character in the series. His first appearance was in the short The Scary Story. In it, he is protrayed as the monster in the story, scaring and eating little Om Nom and scaring Blue Bird in his dreams. At the end of the video, he tries to offer The Angry Birds pretzels, but he ends up scaring them away. His next apperance was in Time Travel Trouble, alongside a Triceratops, where it is revealed that he hates Green Pigs. When he saw one of the Pigs arriving in his time period, the T-Rex, along with the Triceratops, proceeded to beat the crap out of that Pig along with Blue Yoshi. The T-Rex and the Triceratops appeared again near the end of the second part of the episode where they do not only beat the crap out of the same Pig they and Blue Yoshi beat up earlier along with Blue Yoshi, but they and Blue Yoshi also beat the crap out of Chef Cochon and King Pig. He appeared again near the end of the second part of the episode Shark Butt Strikes Back, where he tricks Yellow Bird by standing behind him. When Yellow Bird turned around, the T-Rex is still behind him. When Yellow Bird turned to look, the T-Rex scared him, but leaves.
