Pom-pom, or Apple King, as he is sometimes known, is one of the school's supply of chemistry teachers. His most remarkable characteristic is the way in which he writes on the board notes to be copied down, as he frequently does. He stands, facing the board, and with one hand strategically placed behind his back, he wobbles his head as he writes, moving to and fro across the board in yellow or white chalk.
A common fact, not normally spoken of, is that he has a pet caterpillar, which he keeps in his beard, unlike Mr. Cooper, who at one time had a squirrel on his chin. The caterpillar is green with pink spots, and is quite hairy.
