Buildbots

A gray mob that builds structures, and hates villages. It can build across water, remove lava, dig, and make houses. This is mainly a test to see what the mobs can build, but it can still be fun!

for a fun thing to do with the robots, set levels of oak logs at varying heights. They will try and build up to them and break them.

And if you want them to be faster, increase the tickspeed.

The only way to kill them or get rid of the is TP them to the void.
