Grayscale Escape - Christmas

[Evita]

Stuck with cd, four marbles, screwdriver and toy. I've only gotten into the 3-numbered box. Any hints for the other boxes?

Nevermind, out!

Hmmm, never used the 4-numbered box...

Got out but that slider thingy wasn't working well so it took me a long time to find the safe.
