Sewer Adventure stage in Mason and the Minish Door. When Mason and Sheila reach the part of the sewers just below Mason's house, they encounter this monster as he attacks them in a musical sloprano. They are able to defeat him with giant toilet cleaners and toilet paper. Eventually, Mason and Sheila end up shooting upwards on a huge gush of water, with the Almighty Poo on their tail. They come above Mason's toilet as Aurora and Francis walk in, seeing the Mighty Poo in the toilet. They get a plunger to force him back down before flushing the toilet, and the creature was banished back to the sewers.
