To answer your first question, that would be an Ant Trooper from Super Mario 3D World.

As for your second question, I'm not sure what you mean by "teo," but I'm taking a guess that you meant to say "two." Anyway, I think he left Morton and Wendy as heads, so he could edit two copies of Larry's body and stick the heads on when the time is right.
