MY PET FIREFLY is cousin to the BUTTERFLY IN A JAR. As with the Butterfly, the Firefly responds with various behaviors to different patterns of taps to the cap. 1 tap it lights up and flies, 2 taps it flickers, 3 taps it glows bright and dims slowly, 4 taps it flickers then glows.

There is a realistic version with a green light, and then some more playful versions with different colored lights and small bodies.

My Pet Firefly was manufactured and distributed by Gemmy Industries.
