Leafers

Jason, who is a full timer on Khan Academy, made an avatar naming contest which ended on Nov 15th, 2013 at 12 AM PST(Pacific Standard Time). Sal had to decide out of the top 3 names (Leafers, Sprout and Terrafern). A few hours later, Jason had announced that the name would be Leafers. This name was suggested by Light Runner.

Leafers was the first new avatar on Khan Academy, along with Piceratops, in two years. Many users have the ultimate version of this avatar, which shows you have 250,000 points. That's because it shows a great achievement, and it makes users proud(ultimate version the last avatar in the picture right).

Design
Joseph Lee, a Khan Academy staff, made the design.
