Coach Green is the crazy gym coach at Norrisville High.
Appearance
Everyday
Coach Green is tall and lanky with golden-brown hair and hazel eyes. He usually wears glasses and a white sports jacket with yellow stripes and blue sides over a black shirt. He also has very short yellow shorts, long white socks with red stripes, and blue tennis shoes with yellow stripes.
Personality
Coach Green is possibly one of the most dangerous and insane teachers in Norrisville High, wanting his kids to do things like play hopscotch with a flamethrower involved in "The Tale of the Golden Doctor's Note" and do blindfolded archery in "Sword Quest". He believes in learning by doing, so he sends his students on a three-legged race to the most dangerous places on the high school campus in "Randy Cunningham and the Sorcerer's Key". Despite his wackiness, he has a jolly attitude, always enthusiastic about what he's doing no matter how extreme it really is.
