So if Maximus is telling the truth, Groot has, in fact, been giving practical advice and suggestions all this time? Boy, that must be frustrating for him.
Groot (thinking): I have it! A simple matter of relativistic propitiation of the psychodermic automatons! Clearly, this can be accomplished by pushing that small red button over there - the one that is too small and set too deep for my finger to connect with. I shall alert my companions to this.
Groot (out loud): I AM GROOT.
Groot (thinking):...Dammit. Looks like I'll just have to smash the wall down again and hope that works.
