[Rick and Morty] In s2e10, why was the everything-on-a-cob planet so horrifyingly bad? [Spoilers]

In the episode "Wedding Squanchers", the Smith family escapes Bird Person and Tammy's wedding which was crashed by the Galactic Federation. They find three Earth-like planets outside of the Galactic Federation's jurisdiction, but they're pretty crappy or uninhabitable. The first planet was incredibly small, the second planet had everything on the cob, and the third planet had a screaming sun.

But why did they seemingly evacuate the planet with everything on the cob? Even when they land on loud sun planet, Jerry remarks how nothing's on the cob. So what am I missing that an idiot like Jerry can find instantly? Why is the cob planet so bad?

Everything on that planet was cob. EVERYTHING. Down to the DNA of the things on it. Do you know.how much that squanches with human non-cob DNA.  It's a fucking lot. 

Eventually your own DNA will start to cobify and that is a fate worse than death. Do you want to slowly turn into an on the cob version of yourself? I'd much rather squanch with the screaming sun personally.
