What I found to be the easiest way to get this achievement was to load up area 4, which puts you right before the boss in zone 1. I dodged as much enemies as I could, fought the boss, and got the pop. Literally took me less than 5 minutes and beats going through an entire zone.
Apparently, you can also do this with a friend in co-op if you so choose, though I have not tried this myself. Credit goes to PiCkLE SQU1D for bringing this to my attention.
