When the CHECK it look was introduced in May 2010 the Monday Night promo was changed with a new announcer, a new soundtrack and the new CN logo. Technically, the only new Chowder on Monday Nights was on April 5, 2010 (when the block premiered), so the Chowder part is a lie. Credit goes to levyanime47promos. TM & © 2010-2011 Cartoon Network.
