With global famine worsening, Hasbro pledged an additional 30 white marbles Monday to hippo-hunger relief efforts. 'To see those starving, starving hippos just lying there, not knowing if they will ever get another chance to click and clack for life-giving marblesit's too much for anyone to bear,' Hasbro spokesperson Lisa Reiderer said. 'We cannot stand idly by while these sweet, plastic creatures slowly die. It is up to all of us to get the most marbles for our hippos.'
