Toysmith Brinquedo de Corda Flamingo

I floated this in the bathtub and it paddled circles for a solid minute after just a few twists of the belly mechanism. Way sturdier than the cheap plastic ones I've bought before.

My niece claimed this as soon as it hit the tub. You twist the little knob on its belly and it actually paddles around on its own for a good while. Cheaper than I expected for how sturdy it feels.

Took this to the pool and it paddled in circles for a solid minute off one twist of the belly mechanism. Way more fun than I expected for a cheap little toy.
