Yang discovers something very shocking: the recliner Master Yo regularly sits on is actually inhabited by a bunch of microscopic tiny creatures; naturally, Master Yo and Yin don't believe Yang even though the creatures have made their presence known to Master Yo through acts of retaliation. As a result, Yang decides to use the Woo Foo Battle Cruiser to shrink down to the size of a furry creature to prove his theory, unaware that a mad genius named Professor Whackjob wants to use the Woo Foo Battle Cruiser himself in order to get big enough to boss all of his fellow citizens around. Will Yang be able to stop Professor Whackjob and save Master Yo's recliner from a fiery end?
- This episode features Professor Whackjob as the main antagonist.
- The Woo Foo Battle Cruiser should be destroyed in Moon Over My Yinnie, but oddly the battleship appears undamaged and operating perfectly.
