We also have the fisher price hippo that you can walk with that "eats" the peek a boo blocks. It's not as fun as the stride to ride walker as it does not make sound but you can walk with it or sit on it. Thought I would mention as they may differ greatly in cost. We were fortunate to get our stride to ride walkers on the heinz bar code promotion - with twins we had heaps of bar codes. Good luck.
