Matilda from Angry Birds was originally designed as an unnamed male bird, but was changed to female when Rovio's higher-ups realized that male birds do not lay eggs. The Valentine's Day season of Angry Birds Seasons gave Matilda a girlfriend, which, after the change, retroactively gave the unintended implication of Matilda being a lesbian, despite actually being straight and later marrying Terence in the film series. When Matilda was redesigned for the 2013 animated webseries Angry Birds Toons, she would gain the pink cheeks of her former girlfriend. Angry Birds Seasons was removed from app stores in 2019, completing the retcon of the girlfriend character. Despite this, the Angry Birds franchise would introduce LGBTQ+ side characters and support LGBTQ+ fan works in later years.
