MassHole rubbed his hands together eagerly. “Skidmark, get the construction crew on the line. I want the Mass Jet built yesterday!”

Skidmark nodded vigorously. “You got it, boss! We'll have this baby up and running in no time. Those chumps won't know what hit 'em!”

As construction on the Mass Jet began deep within the bowels of Fart Tower, MassHole couldn't help but cackle with delight. Soon, his ultimate weapon would be complete, and Fartlantic City would be at his mercy.

What upgrade should MassHole add to the Mass Jet?

A. An extra-large fart cannon
B. Cloaking device for sneaky missions
C. An on-board burrito bar for unlimited ammo
