A sketch in blue pencil of McMoosington with a giant preztel-shaped lump in his throat. He looks concerned. And is holding a box labelled "JUMBO PRETZ".

And the following notes to the left of the sketch, also in a handwriting font:

Brainley: McMoosington learns a valuable lesson.

Brainley: (Note to self: Switch to goldfish crackers.)

Brainley: (Addendum, 2 days later: Okay, scratch the goldfish crackers. He just tried to eat an aquarium.)
