Plot
Baby Mario and Baby Peach have been playing the switch all day under a blanket. Baby Peach thinks it's getting too hot, so she opens the window with one of her inventions. It is then time for them to go to bed, but then Baby Peach never closed the window, which caused a bad to fly in the house. It then lands on Peach. Peach thinks it's Mario's Wii-Wii, so then she tells him to get it off of her face, until she then learns it's a bat. She was Mario up, runs to Baby Mario and Baby Peach's room, and wakes them up, warning them there's a bat in the house. The entire house is then alerted, and then Luigi and Toad enter. Baby Mario tries to call the Ghostbusters, but that failed. Mario suggested that they call Robonyan's bat exterminating service, so they did. Robonyan proceeds to teleport the bat away, but he teleported it to the Kitchen. Chef Hal was cooking until Mario pointed the Bat out. Chef Hal then makes a treat so the bat can fly into the treat, and then he'll get clapped. But then the bat flew to Mario, telling him he smells bad. Peach then makes the Bat Catcher 5000, but then the bat takes a crap on the machine. Luigi then has the idea of calling Batman. He calls Batman, and then Batman tells them the Bat Is evil. Then, the family has a fight with the bat, and they killed it..............for now.
