Nathaniel has moved from the demolition to the construction industry. It's very exciting. Previously, if you built a tower of blocks and then put the man anywhere near, it would only be a matter of seconds before it was lying in ruins. However, today he decided to take the oppostite approach and built several towers of blocks.
This is not his best tower as he'd alreday built several by this point, whilst I watched surprised! But it gives you the general idea.
