[Spoilers] How the heck do I get a certain toy

[Istrice]

Hello everybody, I feel I'm missing something, I also looked on walkthroughs and I can't understand why I'm not finding the wooden toy in the gardens, I think I made everything I could up to this point, I had the Fifi's confession about Freya's diary and all...
Is there anything else I have to do?

I'm not sure of the order as I got it, use it but needed to complete some stuff before going forward.
But I know I got it just after going back to the first 'zone' (where you arrived on the island) and add to make some guess (question mark blinking on Sally)

What I can tell you also that should help is that there is a hint system when you open the map, in the top right corner, click on the question mark.
The game will give you a room where you should go to advance.
Go there, click everywhere, interrogate the character on everything if you did not unlock anything (it took me time to realize you can probe them about the other characters, not only with the clues).
