My serious answer is that it could be something to do with temperature.
Perhaps it helps keep him warm, cold, whichever a genetically modified

My silly answers are that Pen-Pen is actually a robot and that's where
the batteries go.

Or...Pen-Pen is a small Mecha piloted by even smaller people and the
back pack is where the entry plug goes :D
