Tyki hopes Strange isn't going to literally stab it because while that would for sure confirm if it was hostile or not it might actually hurt. He sort of can't infuse his Power to Choose onto his tentacles yet and an intent to attack would override that anyways.

His eyes lower towards the dagger that he has with a momentary snort, "That dagger isn't enchanted or anything. I have to ask, knowing you."

But kidding aside he's grabbing for one of the tentacles with both hands and holding onto it rather taunt. It wiggles in his grasp and he has to squeeze hard to prevent that natural smoothness from making it easy to slip out of his fingers. "This should be fine."
