Every bird I can think of, and depending on how you define 'legs', monkeys and apes too. I don't think I'd have thought of kangaroos on my own though.
Like most questions, the answer depends on how you interpret the question - e.g. do meercats count as two legged because they have their front limbs off the ground sometimes when looking about, or not, because they walk on four feet? (I would say they are not 'two legged', but you probably could argue they were depending on how you defined 'two legged').
