"I like that they are a squeeze toy and green is a fun color, but this should not be marketed as a glow-in-the-dark toy. We sat a bowl of them under a light for hours at time and then tested them in a dark room...nothing. We put them up to a bright flashlight Halloween night to see how they would look at night...nothing. I knew this was a possibility when I bought it, so I wasn't completely disappointed. Since it is not glow-in-the-dark it is definitely not worth the price I paid."
