I will never ever allow my child to get one of these and use it inside the house - it created a total clog of the sink - even though I got most of it out. As the blue hair fiber turned into this mush that basically stuck inside the drain.
The toy is an interesting idea and I commend them on that. However, the fuzz fibers are just like flushable wet wipes- they really shouldn't go down the sink.
The toy does react to hot/cold water by going from all black to a white color with clothing on.
The shampoo bottle this little fuzzy friend arrives in doubles as a bag - which is kind of cute and great to be able to store all the pieces in.
Overall, this toy is a mess and creates a bigger mess when trying to use it in the intended way.
