We have a gorgeous wooden one that looks like a bee. I can sit on that one and play on it, but it is ride-on only.

We also have a plastic one that played a tune (batteries now removed) and that was a FP one, from memory. Plastic and ride-on/pushalong toy with a clock at the front. It is still around and Liebs would play with it now if I got it out! If you want to avoid too much noise do NOT get the popcorn ones that make a huge noise when they're used.

Trays with handles and wheels (with blocks in) can topple easily with a not-confident walker. Liebs really loves riding on his so I'd go for one you can ride on as that seemed to be the most fun we had with them (we did races and chased each other riding on the two we were given).
