I made my plastic Ent like the one on the box-front of the Ent... and this is what's left from the spares:
Not much heh?
Each hand can be replaced with a hand carrying a rock and one with a stone (or small rock)... Or you could combine one hand rock and one normal... heh. The two fore-arms are only possible to combine with the rock-hands (empty hands are already in one piece with the fore-arms).
Then the face, and the back of the head which can only be combined together.
There's 2 dead orcs, and two spare twigs.
And that's it... Most of the twigs can be repositioned though, but there's barely differnce between them that you won't even notice from a distance of 1m (or 3ft)...
You can easily position the legs and arms as you wish, although I had a hard time getting it in a natural pose (pinning might have helped...)
To bad you focus on the GW-tournaments. Majestic Bear has some really nice Ent-figures!
