Big Willy is People!

9. Look at My Big Willy

This strip is based on, inspired by, and ripped from Destroy All Humans! Big Willy Unleashed. All the dialogue except the last sentence is from the game's opening cutscene, as can be seen in this charming walkthrough.
 The artwork was also made with the help of that video. I took a screenshot at around 2:40 into the video (just after the aforementioned dialogue) and traced the line work over it in Paint. The result is a really great looking and accurately proportioned Crypto and Pox.
