Psst!
For April Fools' Day 2014, Bailey (or Mrs. Carrot the Carroty Carrot) announced:
Player Changes[]
Players, based on their classes, became different fruits or vegetables:
Healers
Mages
Rogues
Warriors
Hero Changes[]
The modified Hall.
Some Elite and Legendary Heroes (Contributors) had changes to their titles and contributions in the Hall of Heroes. Daniel the Bard (who was impersonating Ryan), Alys, and Lefnire, for example, became "Macaroni Artisan," "Queen of Hearts," and "Burrito," respectively, with Lefnire's contribution becoming "Main contribution = Burrito."
Many of these changes still persist.

Tomayto Tomahto (Ian the Quest Master)

Mrs. Carrot the Carroty Carrot (Bailey the Town Crier)
