Thank you! I’m new, so I obsess about everything. He started out with four heads and now they’re all doubling he came with 2 friends and they’re both doubling as well. One of them is creating a ton of baby heads on his skeleton and it’s fun to watch them grow. I’m still not 100% sure what I’m doing, but whatever it is they like it. Kind of like when my kids were little hahaNice looking hammer!
