War of the Weirds and the Instant Aliens showed up at Granny's house in A Mid-Autumn Night's Scream. John thought they would be perfect in a lunch together and I think the kid was on to something!
Marvin is a turkey sandwich. The Instant Alien is colored onto colby jack cheese. Surrounding them in the box are Goldfish Space Adventures crackers. He'll also get an apple or banana and possibly a yogurt tube or cup depending on how he feels tomorrow when things get packed up!
