Grenade Tree Spawn

This is for the  BnC spawn competition. A good Samaritan offered to send me a bunch of grenades when I said I had an idea for a spawn that used many of them. Here is the beginning of that spawn, please forgive the pictures as I have misplaced my normal camera and have to use my 3DS.

UPDATE: 19.01.2015

Added an arm, still need to figure out what I want to be in his left hand, maybe just tentacles.
