Pinkie is a problem. She doesn't know what I'm up to, but she knows I'm up to something. Hiding something. I keep finding her snooping. I'll need some kind of distraction to keep her from finding the Holopad. Hopefully, she doesn't suspect the microwave.

I concern that Pinkie's Fourth Wall power might accidentally punch the whole Library's kitchen into Barnon's.
