A Mythical Blacksmith and a Real-Estate Dealmaker Pitch Kids on Go-Gurt

That's the takeaway from two new ads for the General Mills brand from longtime agency Saatchi & Saatchi. As in the past, kids play leading roles. But rather than hijinx, persuasion and brute force come into play, plus a dash of drama.

A blacksmith—or rather the Greek god of blacksmiths—is the hero in "Hephaestus," a wordless exchange between a girl and the hammer-swinging craftsman.

In "Real Estate," a well-dressed boy tries to persuade a Go-Gurt tube to give up its contents in exchange for much better digs.
