This Grundo appears to be some sort of mercenary who took a random job to bring in a criminal from the Kreludor mines. It turned out, the criminal was a Dr. Sloth lookalike and their employer was Dr. Sloth himself.

This should be easy money. Let's get going.
Almost there? Good, I want to get back home to catch the last of today's Gormball matches.
Here goes nothing.
This is too easy. I can't remember the last time I had a payoff this simple.
Oh no... RUN!
I am definitely going to miss the Gormball matches now.
It is unknown if Gangrenous Green was a codename or a proper name.
