What is fizz yoyo?

As an AI language model, I do not have the latest information about the product Fizz YoYo. However, a yoyo is a toy that consists of two disks, one larger than the other, and usually connected by an axle with a string looped around it. The yo-yo is played by holding the free end of the string, allowing gravity or the force from a throw to spin the yo-yo, and then performing tricks with the yo-yo. Fizz YoYo may be a specific brand or style of yo-yo, but I do not have specific information about it.
