When Mac arrives, Bloo quickly works to make Mac cool, but none of their ideas work. But just as Mac says he doesn't care about being cool, the coolest kid in the school, Jamez Withazee tells him that the fact that he doesn't want to be cool, makes him cool, and invites him to 'The Rock.' As Mac is not at Foster's at 3 o' clock because Jamez tells him that Foster's is for nerds, Mr. Herriman is very quick to ensure that Bloo gets adopted. Now Bloo must find Mac, while at the same time avoiding adoption! Will bloo find Mac before he gets adopted?
