While usually passive, if it comes out of the ground and gems pop up, DO NOT GRAB THEM. It will chase you for a very long time and does a respectable amount of damage.

Wondering if anyone thinks it possible to kill rock well by useing a well bred roll rat with a Mastercraft saddle ( which I found in the elemental vault) and rolling around the tentacles doing more and more damage as you gain momentum. I think the roll rats turning radius when rolling is perfect for this. What do you think of my wierd strategy?

Roll rats DO NOT swim well.

If running away from one, lead it into deep water and swim around; it will eventually drown.

Piles of loose gems are like wyvern eggs to them, if you take any, instant aggro

This animal is literally based of the naked mole rat

They spawn very often in the area between the blue and green zone, or at least they did for me

Found in the abberation lunar caves of genesis

Don't pick up anything shiny it digs up or it will freak out.

They get agro if you take gems from off the ground and they see you do it
