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

it is now the month of december. since christmas, a tradition that started 2020 years ago is in 17 days, waluigi, who is wario's partner in crime, wants to celebrate. for that, he decided to get a green screen to make it look like he's in front of a christmas sweater pattern and wear a christmas hat (that christmas hat however is tweaked. instead of being red, waluigi changed it so that it's purple, most probably to match the color of his shirt, and he put his emblem on it) in order to pose for a picture. he seems to be pinching his mustache, probably because in his opinion, this pose looks good. mysteriously enough, wario doesn't seem to be in the picture. either he was not here, or he didn't want to be in it.
 
A man made of snow, a snowman if you will, they appear to be in an all white location, they wear a top hat with a red x, having a rather sinister face with eyes in the shadows and a menacing smile, they have 3 black dots on their body and one of their hands are dark blue while the other one is blocked from viewing
 
The above image appears to depict a small portion of some sort of amusement park ride, possibly a ferris wheel, being utilized at nighttime. One of the passengers of said ride is the character "Miles Prower" from the Sonic the Hedgehog series of video games, who goes by the nickname of "Tails". He appears to have died, possibly from fear, as indicated by his pupils being replaced by the letter x, a common trope to depict death in a cartoony fashion, as well as the presence of a nearby ghostly figure resembling him, most likely his soul which has exited his body. The identities of the other two passengers are unknown to me, but they appear to be a pink cat and some sort of creature resembling a cross between a bird and a chocolate flavored ice cream cone. Unlike Tails, these two ridegoers seem to have managed to stay alive and are enjoying the ride, oblivious or indifferent to the fact that one of their companions is now a corpse.
 
It's a dog, but with a brown hat. The dog has black ears. There is a fake mustache on the dog.
 
Princess Toadstool/Peach, ruler of the mushroom kingdom, has decided to become a doctor in order to help ill people. She was known as nurse toadstool at some point, but she managed to become an actual doctor.
 
It's a Toad, specifically a blue Toad and not the red Toad we're all familiar with, screaming in surprise at something. It appears to have Mario's hat on so perhaps it's screaming because it realises that if they have Mario's hat, then Mario is hatless.
 
It is a picture of the person who goes by the screen name "Scott the Woz" on the popular video hosting site known as YouTube. In this image, Scott the Woz is smiling at the camera and is positioned against a blue background, possibly with the intention of digitally editing out the background and replacing it with another image or perhaps video footage. The image appears to have been rotated 90 degrees in some sort of editing program, as humans typically do not take this position.
