Golem transformer

Imagine a block golem that you can take with you. This golem could dig bridges if you give him no more than a stack of blocks.

There are a few ideas on how to craft it:

1. Using a copper block. Perhaps the copper golem could return, and maybe even with the same functionality

2. Using a lapis lazuli or amethyst block. It's time to give lapis lazuli or amethyst more use.

3. It could be found in a chest as a very rare loot.

Аlso this golem will constantly have to be repaired either with amethysts or with lapis lazuli
