When a pen that looks like Abraham Lincoln is caught with a student cheating on a test by Mac's teacher, he is saved by Mac and Blooregard along with his au pair, a green ogre type. The Lincoln pen cons Madame Foster into a new plan to adopt an overcrowded home to unsuspecting adoptors for a fee, then take over the house and plan to turn the home into a casino. Mac finds this out the hard way as Wilt becomes a flagpole and Eduardo becomes a shell of his former self, as it were, and is put with Mr. Herriman and Frankie in a locked closet. What will Bloo do to save the house, and will Madame Foster get control of the house back?
