Describe the above user's avatar in way too much detail

A dish full of bolognessa-type spaghetti, with tomato sauce all over it, two black round eyes, two meatballs, a white background, a knife and a fork, and some Spooktober theme to spice it up.
 
It is a dark blue sky with a bit of orange-ish lighting near the bottom, signifying that it is either sunrise or sunset. There are two objects, likely shooting stars, falling from the sky. The two objects diverged from the same point, which is indicative that it was one object that split into two in Earth's atmosphere for some reason.
 
some kind of adult who called himself "Dr. Peter Venkman". he looks to try and be cool by wearing shady glasses, he might even have the job of the ghost busters (I'm sorry if I'm wrong I don't even know who he is lol). He's also implying that he isn't afraid of ghosts, meaning that he has already seen one in real life, or else it would be meaningless.
 
A planet similar to Earth with a blue background and a cloud, with a Castle with a red roof, a hill in the middle of the water, a brown living mushroom with two white eyes, a mouth, two fangs, and two feet with no arms, legs or hands. There is also a round white ghost aside the castle, Mario with the wing cap looking at the camera, and a grinning face, and a Super Mario 64 logo.
 
A yellowish dragon-like creature, in the slender style more common to Eastern depictions of dragons. It has its mouth opened and its eye closed in a style that indicates it is happy about something, although there is a large booger dripping from its nose. It is inside some sort of container and looks like it's phasing through it, with it's claws sticking out of the front of, perhaps indicating that it can become noncorporeal? There is lightning all around the creature, a sign of lightning/electric powers.
 
A black train with a grey face and a red front part. It has a cloud and the sky as a background, with a smoke column behind it.
 
this following picture seems to have a cat on it that strangely has a human body, it also seems to be holding on a card which seems a bit precious to her. this cat is colored with the color pink and has big ears.
