mr. rabbit (brown) (rusty lake)
A character in the Rusty Lake series, first introduced in Rusty Lake Hotel.
He is a rabbit furry with brown fur.
He dresses formally, wearing a traditional black bowtie, a white collared dress shirt, a plaid black tailcoat, a red waistcoat, a pair of black dress pants, a pair of white gloves, and a pair of white shoes.
Note that this Mr. Rabbit and the white-furred Mr. Rabbit featured extensively in Cube Escape: Birthday are formally treated as separate characters on Danbooru due to plot ambiguity on whether the two are the same person or not. The other Mr. Rabbit can be found under Mr. Rabbit (White) (Rusty Lake).
