The Flummy Disco delivers what it promises: If you drop it, he jumps wildly blinking through the area. He liked me and my children immediately. The blinking stops about 20 seconds and then you can the Flummy also without blinking in different colors light, admire. The Flummy is translucent but not clear but has triangular facets, but are inside. He is filled with fluid, floats in the colored glitter. We ordered 2 Flummies and one in green and get in orange. According to our calculation, you can contact the seller with a color request. We did not know, but are satisfied with the delivered randomly sent colors. In addition, in the liquid floats a ball in which the electrical and the lights are. It is impossible to change the batteries. I certainly hope that the two sides consider relaively long. But this I can not say anything today. What I also like is that it as far as I can tell, is handled properly and does not smell unpleasant.
