Thanks you for your advice, and for your comment.
I have to apologize because of my grammar mistakes, English is not my first language; so I'm sorry.
And I really apreciate your ideas. I was thinking about symetry too, but a cube monster with five side blocks ... Wouldn't it be so big? But if they think it's ok ... Nice!
Yeap, what I meant with lianas was vines, thank you for your help!
