No batteries needed - ever!
Just slide a lever on the side of an Ecotronic Zoo Flashlight and a wing - or a leg - or an appendage - will appear. When this is moved in and out by squeezing the body of the animal, it primes the energy source inside the flashlight that powers two well-placed lights (top of head and front of face).
This brilliantly-designed product is fun plus therapeutic for building finger and hand strength. Assorted styles include: dog, pig, cow, and duck. Price is per flashlight.
