"I'm Angry, But I'm Happy!" - Red The Loud Engine's official catchphrase.
Red The Loud Engine (Gunnar Tarbox) is one of the main villains and heroes in Macy's Parade Mysteries.
Red is depicted as a very happy and fun-loving bird who loves being a chatterbox, and rarely gets angry. One of his favorite activities is to collect and build LEGO sets (Ninjago being his favorite theme) and playing video games, and offers his friends to help out with his collection. His group of friends include Jumping Janie (Idol Balloonatic), Catherine the Wish Maker (best friend), Shea the Superstar (second best friend), SpongeField AlphaLoud (third best friend), Aviator Mickey Dragon (fourth best friend), Captain Candy, Jay Marcus, TNT, and Polar the Robloxian.
He is a red bird with a tan stomach, similar to Red the Angry Bird. He also has Lincoln Loud's hairstyle, Harley Quinn's hair color and Thomas the Tank Engine's wheels, making him one of the only transportable characters in the franchise. He also has Thomas' whistle as his bird call. He also has a twin sister, Stella the Loud Engine.
