Stanley Sunday

Stanley Sunday is a minor character in Katrina Sunday's videos. He is Stefan and Riley's adoptive son, James, Katrina, Anouk and Mara's adoptive brother, Katharine and Kaleb's adoptive cousin, Marie and Jake's adoptive nephew and Gerda and her unnamed late husband's adoptive grandson. He is an eleven-year-old preteen grey tabby cat, though he is eight in the Katrina Sunday Movie.

Personality
Stanley is a mischievous, rebellious, scheming and food-motivated preteen boy. Despite his mischief, he can be affectionate to his family. He loves fighting with Mara since they're siblings.

Appearance
Stanley is a grey tabby cat. He has green eyes and five whiskers. He also has a dark brown nose. His attire consists of a light blue baseball cap, a raspberry hoodie and gamboge pants. Unlike the rest of his family, he does not wear any footwear. Instead, he is barefoot.

In the final concept of The Katrina Sunday Movie, he wears a tan sweatshirt with brown cuffs and a brown collar, cornflower blue pants.

Mara
Stanley and Mara are brother and sister. Stanley pulled a prank on Mara by throwing poop at her. This got Mara mad and she chased him away from the kitchen as seen in "The Katrina Sunday Movie Idea 2".

In the final concept (and first clip) of The Katrina Sunday Movie, Stanley also threw poop at Mara. However, Mara merely threw fire at Stanley as a revenge.

Katrina
Katrina is Stanley's favourite sister. He is said to follow her and ask for attention often. He likes hanging out with her, though he will occasionally fight her.

Trivia

 * He is based on his real-life self, Mickie the Cat.
 * In the final concept of The Katrina Sunday Movie, his attire is similar to Gumball Watterson's from the Cartoon Network show The Amazing World of Gumball. However, his pants are cornflower blue rather than grey.
 * Like Gumball, he is a cat who has six whiskers, with only five being visible. However, unlike Gumball, Stanley is a grey tabby rather than a blue cat.
 * He is the only member of the Sunday family to not wear any footwear.
