The series follows a ritualistic pattern and centers around an assortment and musical pop group of neighboring playmates depicted as bipedal, anthropomorphic animals: Uniqua, Pablo, Tyrone, Austin, and Tasha. Designed to encourage imaginative play, the characters communicate with the viewers by constantly breaking the fourth-wall, albeit the series rests particular focus on the role-playing games in which the friends participate varying with each episode, and said games are visualized through dream sequences lasting for a majority of the episode and serving as the primary focus of that certain episode. Usually, the group will visualize a unique scenario, ranging from prehistoric times to adventurous fantasies, and they are often presented with multiple dilemmas along the way to accomplishing a certain goal or priority, or may be challenged with a major single obstacle to defeat or problem to solve. After season one, there is usually a villain in the episode, mainly played by one of the Backyardigans (thus another Backyardigan plays the role of the hero), but the villain of the episode always reforms in the end. The program also follows a musical format, featuring multiple musical numbers sung throughout the course of an episode regarding whatever imaginary predicament in which the characters have situated themselves or perhaps a challenge that they have met, every episode opening and concluding with a particular song. The adventures get more advanced after the first season. When the Backyardigans have achieved their mission or defeated any disadvantages, the fantasy sequence fades, restoring actuality to the setting of the episodes as the closing song is sung, the characters scurrying to their houses for a snack. The main character or characters then opens the snack host's house door, fence, or around the corner, and shouts the main catchphrase for the last time and then closes the door. The picture then is lifeless with some background bird noises often heard as iris closes, ending the episode.
