Also seems like in the story at the begning the fish was freak out like just freak out when the cat started to as the narrator and sally if they want fun. I find that is superego because superego could be like they get freak out at very little when they think that it's not right. Also the fish was not just freak-out it, seems like it was yelling at the cat and the narrator and sally that they are doing something wrong when thier mother is not home. Also seem like the fish is babysitting the narrator and sally instead of they babysitting themselves.
Towards the end the fish was kind of id because when it notice that everyone doesn't seems to pay any attention to it, so it seems to be acting like a child. The fishing starting to act like child, by not liking everything that is around, which he never really did in the first place. Also being selfish when he knows that the narrator actaully took actiona dn try to scoop up thing one and thing two. The fish seems to be happier toward the end because they cat is gone but still very mad because everything was all mess-up and out of place.
In conclusion, i think that the fish in, "The cat in the Hat" is superego at the begining of the story and id towards the ending of the story. The fish was like a babysitter for the narrator and sally but was acting like a child towards the end of the story. And it seems to be ego again at the end of the story when thier mother returns home. But through out the whole story the fish was superego and towards the end he was kind of an id.
