Ecotronic toys offer kids all of the lights and flash without the worry of having to change batteries.

To bring these toys to life, all you need to is wind them up or give them a shake, the dynamo inside will do rest.

The best part: unlike their battery operated counterparts, ecotronic toys never run out of juice.

This is where Sprig comes to the rescue. The eco-friendly toy company has created a line of toys that are complete with all the bells and whistles, with one catch – they are powered by your child!

Sprig’s Adventure Series trucks (priced between $20 – $50) harnesses the natural kinetic energy of push- and pump-action play to generate lights and sounds – all without batteries.

Although every Sprig toy is built for a happy planet, tough terrain is no match for their sturdy, earth-moving Eco-Trucks. Playing in sand and dirt is good, clean fun with the Eco-Trucks Excavator($14), Loader($14) and Dump Truck($14).

*Eco-Bonus* Designed for the active preschool child, all vehicles and character bodies are molded using SprigwoodTM – a durable, child-safe, bio-composite material made from recycled wood and reclaimed plastic.
