Marc has developed several new words. I expected Big Bird, Zoe, Ernie, etc which he's all started saying recently. However I didn't expect Argh! and Yeti Yeti Yeti! LOL I can't believe that one of my son's first words is yeti. :) This is thanks to the reggae style song A Pirate Says Arrr and the James Brown style song Do the Yeti Stomp.
