Fleeceball is a sport played at P.S. 38.
Fleeceball is said to be very simple by Nate. It is similar to baseball, but you play it indoors instead of outside. The rules are mostly the same, except for the bat you use a broom handle instead of a typical baseball bat, and the player uses a soft, puffy ball instead of a hard ball as used in Baseball.
Currently no injuries have been recorded for playing Fleeceball, except for when Randy Betancourt stomped upon Nate's foot as revenge for his humiliation. However, this was deliberate. The only time somebody risked injury was when Chad Applewhite got "drilled in the face" with a ball while playing Fleeceball, but afterwards Chad turned out to be great, with him claiming to barely feel the impact.
