The "Boom" was fairly straight forward as a suicide bot. I only needed 4 thumbs and 3 of them incorporated the Sea Mine shape as its core from the start. I wish I had had the time to do a quick block model of the sphere and detection horns to keep them properly distributed and in perspective but I think it came together well as is.
The "Leech" was a bit on the complicated side but came together as something you wouldn't want to hug you so... Mission accomplished!
