Works great. It's a great honor that Theo trusts me to raise one of his extraordinary creatures. It looked so helpless and vulnerable when I opened the box. It clearly wanted to be assembled. But without any instructions I was afraid I would harm it. But I also didn't want to leave it alone and look for instructions. So I tried to find out what part needed to go where and I assembled it very carefully. And with a little help it quickly learned how to walk. And after only 1 day all I need to do is point a small fan at it and it starts to walk. Very confident while making a satisfied noise.
