Thanks, Jetoar, Ana, and Adam!

Very nice! And I like the info too
However I think, the base is optional because kids like playing by figures and not all of them display their toys on shelf, so it can basically lay in toy basket between one playtime and another. 
Okay, thinking of it - as a toy for kids that would probably be stored in a box together with other toys the stand is probably not neccessary. But for collectors who want to display the sunfish in a shelf I'd say it's mandatory to get the stand, too.
The sunfish is such a weird creature! We have one on display in our museum 
I remember having seen a photo of it!

Sigh, nearly ten years ago I missed the opportunity to see one in the wild when I collected the samples for my PhD thesis off Galicia. Sampling took ten days or so and the research vessel always returned after one day and so we could choose if we go aboard or stay in the laboratory to sort our samples. The sunfish was of course seen when I was in the laboratory...

I've been told it was a small one, less than a metre long, but still I was quite envious. I did see Pilot Whales,
Globicephala melas, though, which were inquisitively swimming around our research vessel once.
