In keeping with the nickname Fighting Irish and the Irish folklore, the Leprechaun serves as the Notre Dame mascot.
The Notre Dame logo features a side view of the figure with his dukes up, ready to battle anyone that comes his way. The live version is a student, chosen annually at tryouts, dressed in a cutaway green suit and Irish country hat.
The Leprechaun brandishes a shillelagh and agressively leads cheers and interacts with the crowd, supposedly bringing magical powers and good luck to the Notre Dame team.
The Leprechaun wasn't always the official mascot of Notre Dame - for years the team was represented by a series of Irish terrier dogs. The first, named Brick Top Shuan-Rhu, was donated by one Charles Otis of Cleveland and presented to Irish head coach Knute Rockne the weekend of the Notre Dame-Pennsylvania game Nov. 8, 1930.
A number of terriers later took the role of the school mascot, which usually took the name Clashmore Mike. The Clashmore Mike mascot last made an appearance on the cover of the 1963 Notre Dame Football Dope Book with coach Hugh Devore and captain Bob Lehmann.
The Leprechaun was named the official mascot in 1965.
