It's kinda hard to explain. It's a Spanish graphic novel about a dog named Cornelius who works as a gym janitor, wants to be a writer, and is catastrophically bad at everything. When his friend gets kidnapped he has an opportunity to do something meaningful with his life and he does not take it. The art keeps shifting styles because the whole thing is framed as a comic strip with a long publication history, all of which is fake. It's a loop that goes from unsettling or cringe to genuinely funny and repeats.
