Chicken
Big Red is not a decorative character found at the end of the Sewers. It serves as a way of transporting the player to Chicken World, albeit in an unconventional way that contrasts to the aesthetics of the previous area.

It is seen as a large red fetus resting on the ground with a huge gaping toe. It has 4 strands of red hair and a big eye as well. It does not move or react to any of Madotsuki's effects. Aside from Madotsuki herself, the whole screen is shown in shades of red and black. Like other decorative characters, it appears suddenly and is very imposing in the way it takes up most of the screen, And holy jesus they are terrifying.
When Madotsuki walks into Big Red's mouth, she is abruptly swallowed and transported to Windmill World. It will swallow her even when using the Stoplight or other effects. This can be quite frightening to players if they do not expect it.
The music that plays here is the same one used in the main area of the Mall.
