You were standing at the edge of a river when you saw a huge metal shape slowly walk towards you. As the shape got closer, you realized it was some sorta t rex robot, almost twice as tall as you. The robot had red lights shining from its eyes, and it looked like a 40-foot-tall rex with metal skin.

The robot approached you and grunted, "Friend?" You was taken aback by the robot's appearance but realized it meant no harm and speak like caveman. The robot extended its hand, whats do you do? :)
