In the Chica's Room episode "Chica and Her Special Friend," which is based on the Blue's Room episode "Meet Blue's Baby Brother," it's Friendship Day in the playroom and Noodle, Miles, Banjo, the Sprout House Band, and Easton are there alongside the regulars, but someone's missing, so Nina and Chica skidoo into Monsterville (from several Justin Holbert GoAnimate videos) to find them and play Gold Clues to figure out who it is. They come across Star, who has no idea how he got there, by the train station, and visit ABCs Monster, Colors Monster, and the Phantom Princess while finding three clues and sitting in the Golden Thinking Chair on top of the hill. It doesn't take much time for Nina to realize that was Chica's best friend, Star, all along, so they bring him to Chica's Room to join the friendship team!
