My lucky piece of coal

[XANACodeLyoko]

[Deep Sleep] So in the 1st game, you can pick up this piece of coal in basement, but i didnt find any use for it, again, so is it just a reference im not getting? I got the cinnamon toast reference in the final game, but it's just a piece of food you can click for some info, while the coal goes actually into your inventory, so my question is: What/who does it refere to and is it item usable anywhere for small secret or something?

And the golden statue, what it is for :l

#1. according to dev:
The "lucky piece of coal" item in Deep Sleep has no use in game and is a reference to Broken Sword.

#2 There is a gold statue on the top shelf of the bookcase that you can take, but it serves no purpose. The developer of the game revealed it was a reference to "Stephano", a talking gold statue from a PewDiePie Let's Play of Amnesia: The Dark Descent.
