Dr. Diminuitive hangs them all off the edge of the apartment and drops them 40 stories up, but Agent P uses his grapple gun to catch the particle bubble-inator to trap Dr. Diminuitive in a bubble and saves them by using it to create a bigger bubble, which they ride into and Doofenshmirtz taken them to safety and later crash into Monogram's office.
