The weekend has come and Leonard has challenged Scott to a round of laser tag and a pizza-eating contest at the mall which is what Leonard hopes to finally beat Scott at. However, Principal Strickler has to go to a principals convention and as his mother can't take care of Tallulah overnight, he asks Mary Lou to take care of her for him to which she agrees to.
Scott is shocked because he can't go to laser tag with Leonard and the worst part is, Tallulah would know he's really a dog. Leonard sees this as an opportunity to finally win at something and impress the others. But, Scott has a plan to get out of this mess.
At home, Tallulah arrives and Mr. Jolly falls in love with her. When Strickler leaves, Tallulah proves to be the worst cat to take care of as she wreaks havoc around the house and nearly jeopardizes Spot's plan as she almost makes him spill the beans about his identity as Scott Leadready II.
