"Potions, Lesson 1: Don't forget a Sloth brain."
Gryffindor Notice Board during the 1991-1992 school year[src]

A Sloth Brain is the brain taken from a Sloth, which is used as a potion ingredient. The mucus from the brain is a key ingredient in a Dragon dung Fertiliser.[1]

History

Sloth brain

A jar containing Sloth brain mucus

Many older students at Hogwarts favour stealing sloth brains from Severus Snape's secret stores, and splattering the mucus on the floors of corridors, much to the displeasure of Argus Filch, the caretaker.

During the 1991–1992 school year, Fred and George Weasley stole a sloth brain from Professor Snape's stores and hid it somewhere in the Forgotten Grounds. It was found and retrieved by Harry Potter, who brought it to the Potions class.[2]
