Our Crew Is Replaceable. Your Package Isn't.

by Greg Lohman, Thomas Snyder, Dan Katz, and Michael King
Answer: SMITHERS

This puzzle consists of six different "river crossing" problems involving the Futurama crew. In each case, packages and beings must be exchanged in a careful order so that incompatible things are never together. For each mission, there may be some flexibility in which crew members come and go, but the order of packages is immutable. Acceptable solutions for the six missions are given below:

Mission 1

Mission 2

Mission 3

Mission 4

Mission 5

Mission 6

The first letters of each package will fill in the grid as:

123456
1AMYIMP
2ERSONA
3TEDWHO
4MINCRO
5SSOVER
6CRISIS

This spells AMY IMPERSONATED WHOM IN CROSSOVER CRISIS. In the Futurama/Simpsons Crossover Crisis comic series, Amy disguised herself as SMITHERS.
