In the game 'Poppy Playtime: Chapter 3', which smiling critter is determined to be the leader of the critters?

DogDay is a toy produced by Playtime Co. debuting as a minor antagonist in Chapter 3: Deep Sleep. DogDay is the proclaimed leader of the Smiling Critters, which later stood after being transferred as an experiment for the Bigger Bodies Initiative. DogDay originally coexisted in harmony with the Smiling Critters group, each having their own corresponding Bigger Bodies experiment. Following the events that took place during The Hour of Joy, the gang began to drift apart, leaving DogDay as the sole survivor. CatNap then imprisoned DogDay in a concealed cell within the Playhouse, subjecting him to endless torment due to his disobedience to The Prototype.

DogDay is an anthropomorphic canine, characterized by an orange fur that complements his expressive black eyes, floppy ears, and sleek black nose. His features extend to a sunshine-yellow outer mouth and belly, while a touch of Golden-Brown graces his paws, ears, and the left side of his face. In line with other Smiling Critters, DogDay sports a perpetual wide toothless grin, his inner mouth shrouded in mysterious darkness. A distinct black zipper gracefully traces down his center, showcasing a captivating gold sun pendant surrounded by radiant orange sun rays.
