the commands are as follows.

Excavate (any number)- digs a pit straight down depending on the number and make sure the turtle is facing the direction you want it to dig it always goes straight depending on the number and then turns right then goes foward depending on the number.

tunnel (any number)- digs a number X number tunnel so if you put "tunnel 3 it digs a 3x3 tunnel in the direction the turtle was placed

hope this helps, post a reply on my wall for a reply
