Matilda was one of the three angry birds along with Chuck and Red only seen in Sonic For Hire: Angry Birds. She's one of the three female characters with manly voices, along with Candy Kong and Wreck-It Roseanne. (This was probably because the video was made before her gender was established). After Sonic gives them gum, Sonic then tells them it's his own recipe and was made alka seltzer and rice and would blow up their stomachs. She died later on and is used to make a 'kickass omelet'.
