This set of Tropical Fish Wind-Ups lets you wind, release, and watch four bright plastic fish wiggle and “swim” with flapping fins. Each 4.5 inch fish comes in an assorted tropical color, making them fun to race, trade, or line up for goofy undersea adventures. They’re a charming nod to classic wind-up toys and an easy pick for party favors, goodie bags, or anyone who loves a little bit of old school mechanical magic.
