^ Only what is official is canon. It's not opinion. It's what the company says is official. Therefore, by default, the series, and all the comics and books, are semicanon. Fans can't change that.
There were a few references to the human world because it is kind of unavoidable, and as it was there weren't stores or human objects the characters had access to, and that's what I meant. It's not like a human city is what a meerkat colony would be like.
Whether or not a person feels sorry for the character depends on the person, and in the movie, he didn't leave his post. He still failed to be sure, but he didn't do it deliberately.
And you can't boast your opinion as if it is fact.
And the answer to your last question, since you wanna have attitude, it was for the sake of comedy.
