Mike runs to his deodorant-stick hideout, but the girls seem uninterested in following his plan. Instead, they run out to the edge of the desk, jumping and screaming as they try to get the giant bitch Megan's attention as she looks around Mike’s apparently-empty room to see what was making that squeaking sound. Just as Megan starts to turn around to leave, she glances down at the desk and sees the tiny girls.
They explain everything: how he shrunk them, how he shrunk yourself to join in, and how he managed to screw it up so that the gun was on the shelf above your desk.
Megan takes the gun and looks at it, and she's confused. She doesn't understand how a gun could shoot something other than bullets. But the girls keep explaining, and they convince her.
"Oh, I get it now," says the giantess. "This is neat."
