Stuck after hazelnut

[Polar50011]

I opened the second hazelnut in the tunnels.
I got the propeller.
Nobody will talk to me.
My tasks are now:
-Figure out what to do with propellers (joe and bess gave me hints)
-Figure out dodo box (i can't move the figurines so i don't know what to do with that)
-Figure out the second message using the decoder...(but what message?!)

Thank you for all help :)

Is Minette in her office? If not, try looking around in there for some sort of indentation of what you should do.
