I decided to make Nick's dream true, and my gift for him is a ball with the shape of a happy face so he can become a huntsman and play with them with his hew happy ball face!
My gift to Nick is rather fragile, but I know he will take good care of it and I will bring it well wrapped.
Of course as a ghost, Nick doesn't need much since physical objects have little use to him, but there is something I think he might enjoy having: A glass head, like the ones they display hats on in stores. I bought him one of those. That way he can participate in all headless-related activities with a 'prosthetic dethatched head'. Of course it's made of glass and would break quite easily, so I made sure to make a plastic cast of it too so he has something that can take a bit more rough treatment. What is important though is that it has the right amount of transparency, so I painted it with a solution that matted it, so it looks as real as possible.
So happy deathday Nick, I hope you like it.
