Ozu decides to take a vacation- his first in several decades. Before going, he reads off a long list of rules- most importantly, not to harm his prized 500-year-old Bonsai tree. Of course, even before he reads this, Mikey accidentally sets the tree aflame. Now, Mikey and most of the gang (excluding Lily, who is their temporary boss, and doing all she can to keep them busy) must work to replace the Bonsai before Ozu gets back from his unusually short vacation.
