"Doug's Mural Mania" is the 25th episode of Doug in the Disney era. It first aired on March 1, 1997, on ABC.
Doug enters a school contest to paint a mural on a new school wall. Mrs. Perigrew and Principal White match Doug with Roger to paint a large mural. But when he has to share the mural design with Roger, he's not sure he can do it with him because he thinks Roger can't really draw. Also, Bluffington is in a heat wave and the Sleech twins think it is their fault, so they set out to change the hot weather.
