KKG has the owl, the key, and the fleur-de-lis.

Officially, Alpha Sigma Phi's symbol (it's not called a mascot) is the mythical Phoenix rising from the ashes, symbolic of the time when the original mother chapter at Yale died and a little college in Ohio (Marietta College) kept the fraternity going until Alpha Chapter's rebirth in 1907.

Delta Gamma's mascot is the Hannah doll. She resembles a Raggedy Ann doll. :)

Re: What's Your GLO's Mascot??
 

Alpha Phi Omega has 3 'living' symbols: the Sturdy Oak, the Forget-me-not, and the Golden Eagle, but we have no official Mascot. There are some unofficial ones out there in certain sections/regions of the fraternity.

Pi Beta Phi's symbol is the arrow.
Our national unofficial mascot is an angel.

Edited to say:
Oh yeah, the TKE mascot made me smile. :)

National: the owl
Psi Gamma Chapter: the chili pepper because Chi Omegas are RED HOT! :D

The Fraternity adopted Al Fuzzie teddy bear as a mascot in 1974. BetXi Bear mascot was adopted in 1989. (from fraternity website)
