Null is not a morning person. Her alarm clock is a brick of C4, followed by being mechanically dumped out of bed into a shoot, and dropped onto the floor by the breakfast table.
Peta is not a breakfast person. She is in fact a robot. After projecting a fake-out holographic breakfast, complete with color control sliders, Peta offers Null deep-dark-fried-rice. Also a bamboo shoot.
For the next 3 minutes, Peta tries to feed this clearly evil slop to Null and Null tries to DESTROY HER ROBOT SISTER. There are explosions, mecha, more bamboo shoots, and another missed day of school.
Null Peta may only be 5 minutes long, and more than a minute of that is taken up by opening credits! However, the script is packed with verbal timing humor, silly ideas, and good enough visuals to make those 5 minutes enjoyable.
