From an in-universe perspective, why did Crognard end the way it did?

So as we all know at this point, Crognard ended with Crognard getting eaten. Considering the real life purpose of Crognard is to be a foreshadow joke, it's pretty funny but I have to wonder what the in-universe reason for killing Crognard was. Was the series cancelled? Was there some deeper meaning you had to have watched the other episodes to understand? Did the writers just hate the character and used the very last episode as a middle finger to the fanbase?
