All of the scenarios mentioned in the comments are due to the writers' desire for comedic effect. I don't believe the writers meant for Plank to be considered alive in any way, shape or form; his purpose is to strengthen Jonny's portrayal as a loner figure who must imagine someone to talk to because of his incapacity to do so with others. Plank's occasional personification is meant merely to amuse the audience.
