Are baboons the only ones who have pink butt?

Baboons are not the only animals that have pink butts. Many other species, including humans, can have pink butts. In humans, a pink butt is often caused by a condition called erythema ab igne, which is a reddening of the skin caused by prolonged exposure to heat. In other animals, a pink butt may be due to a variety of factors, such as genetics, diet, or health problems.
