BUT: water very difficult to bring out (it must put the head down and press hard). And even then, it rots inside.
I cleaned it several times (huge black dirt came out of the mouth). It takes a lot of time (put some soapy water, shake off the dirt, take out the dirt, x times) and no time was no different, we must start again.
We should buy one every month ... (and again I'm not sure she remained clean for so long).
Finally I threw it and I bought some bath toys more convenient.
