My very first toybiz figure was this one: Treebeard.
I got my hands on him for low price on ebay. A must-have at first sight.
BUT he was way to small in comparison with the 6 inch figures...
Here on figurerealm someone made a custom with larger legs and a better beard than the plastic one.
I cannot find the post anymore, so alas, no clue who was my inspiration.

What I did was making four cuts: both upper- en lower legs. I placed in a big screw through a winecork as leg extension.
After that, it was filling up the legs and scuplting treebark over it.
I added real moss (the beard) and plastic foliage and train modelling natural pieces.
And did a repaint.
The arm broke of, so I had to repair that along the way. Old toys they remain to be.

It has light-up eyes and a moving mustache when speaking its lines in the movie correct voice.
'Burarum!'
'Don't be hasty'.
'I told Gandalf I would keep you save and save is where I'l keep you!'
'Treebeard some call me'.

Fantastic figure. And very intimidating now with the extra length. Enjoy this figure!
