I had this little guy sitting around for a while and I finally got around to finishing him. It took me a while to find something good to use for the spikes. He wasn't difficult to assemble, just needed figure out what parts to use. I couldn't find a good way to attach the antennae/smokestacks so I cheated and used superglue Here's Bob: He's a little big for the rest of the kreons but he's huggable size for the full sized figures I played around and made some photo instructions if anyone wants to make their own.

Thanks I don't have a Sunstreaker figure so I used Whirl as a stand in. Best I could do for Sunstreaker was my little kreon version of him.
For anyone interested, I've uploaded the instructions to build your own Bob to Tumblr for easy viewing
