Shelby makes his debut in the cartoon "Donald's Shell Shots", where Shelby is meant to take a photo at the mall. However, Donald is the photographer and matches wits with Shelby. Shelby would later go on to star as an adversary for the duck much like Chip and Dale or his nephews. Shelby also went on with Mickey Mouse and Goofy in the cartoon "Babysitters".
Shelby is often seen causing trouble for Donald Duck, or rare to Mickey Mouse. He doesn't speak, but he is famous for his trademark laugh. He also can speak in thought as seen in "Donald's Pool". Shelby's mother, Mrs. Turtle, is overprotective of her son and will often yell if she can't find him, or if she gives someone an order.
Trivia[]
Baby Shelby was not yet given a name in the Pluto cartoon Pluto's Surprise Package. and his appearance in the cartoon is considered to be a "prototype" Shelby, as he looks exactly the same with different color schemes and his face was slightly redesigned in Mickey Mouse Works, but his original design was used again later on in the series and in House of Mouse.
Baby Shelby could be named after Carroll Shelby, as well as the car manufacture he founded.
Daisy's Big Sale was the only cartoon where he doesn't appear with his mother, it's unknown if she made Donald take care of him again and that he was making trouble while his mother was at the bow party.
