Toysmith Pato de cuerda

Took this little guy to the pool and the kids fought over whose turn it was to twist the wind-up knob on the bottom. It paddles around way longer than I figured for a cheap plastic toy, and it survived getting dunked about fifty times.

Bought this for my toddler's bath time and it's been a hit every night since. You just twist the little knob on the bottom and it paddles around the tub on its own, which keeps him entertained way longer than I expected for a plastic duck.

Bought this for my nephew's bath time and he refuses to get out of the tub now. You just twist it a few times and it paddles around on its own for a good while. The plastic feels solid too, survived being dropped on tile twice already.
