unmaped theme park or hoax

https://www.openstreetmap.org/#map=19/49.71675/12.97842&layers=N is either a new theme park or a hoax.

I expected to be able to google something about just opened theme park, not yet visible on aerial images but I failed

Is it possible that somebody would verify this object?

I’ll send it to the more active talk cz list, but IMHO, it is hoax (probably pokemon) and all the additions from user mistiblu should be reverted.
