Saanga grunted as the arm slammed against his shield, forcing it loose with it's jarring strike that was further assisted by the fingers wrapping itself around the edges, leaving him with no hope of standing his ground while maintaining a hold of his shield. Oh well, it served it's purpose of allowing him to get in close and it was now a worthy sacrifice. As such he promptly let it go, and as it whizzed away from him within the mech's cold, metal grip, he lunged forward in an attempt to grab as high up onto the right leg with his right hand and legs holding on for dear life. 

His left hand didn't join in on this effort because it would extend upwards and begin to take the form of a ten inch long dagger. If all of this plan worked out then he'd try to navigate up the mech with his right hand and legs while the dagger finished it's formation in 3 seconds time. Then, if he still managed to be alive and kicking and his plan still in the works, he'd begin stabbing at all the joints he could find; knees, hips, and shoulders if he could reach them.

However, if he was interrupted by arms moving in to attack than that would become his new priority target to try and joust at as they got closer. He wasn't sure how well the mech would be able to use it's guns on him while he was on it's body, but if it did bring a gun facing sidewise to shoot across the front of it's body, thus hitting him and not itself, then that would have to bring the gun awkwardly pointed and very close to Saanga due to the max length it could hold out it's arm and point the gun back across the way, so he'd have a good chance of being able to slash at the gun to hopefully damage some of it's parts.

If he got knocked off...well...that was the worse case scenario so he put priority on not getting knocked off.
