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.

A new Kappa Mikey game is released and Mikey goes berserk trying to get a copy.

However, Mitsuki is quite suspicious- does Mikey really have a car, a boat, and memories of a trip to Venice?

While horsing around, Mikey and the gang discover a secret floor in LilyMu Towers. Inside, they find a mad scientist and his enlarging ray. Gonard gets hit with the ray and now its up to Guano to use it on himself and defeat MegaGonard.

When Lily gets sick of Mikey's pranks, she becomes allies with the evil Phantom of the Soundstage. After the Phantom takes it too far, Lily must save Mikey before the pranks end his career.
