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.
An anthropomorphic feline hero with light-gray fur. He is wearing a red cape which reaches down to his legs, a black sweater, dark blue pants, and brown boots. In addition, he has a sword sheathed behind him, along with bluish-purple claws. The entire avatar is done in a pixel-art style.
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.
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.
The popular Mario character Yoshi, who debuted in the video game Super Mario World, which was originally released in 1990 in Japan as a launch title for the Super Famicom and later in 1991 and 1992 as launch titles for the North American and European/Australian versions of the SFC, the Super Nintendo Entertainment system. The character is a green dinosaur that appears to not be based on any real species of dinosaur, but rather just a generic 'cartoony' one and is looking happy, as the character generally is, and is grasping what appears to be a Yoshi egg in its hands. One of the defining aspects of both the character Yoshi and his species, also referred to as Yoshi in the Mario universe, is the ability for all Yoshis, regardless of gender, to lay eggs.
a train to seem well-known for doing its proper tasks, it apparently was built for this and it serves its purpose well. the designers also gave it a face to make it seem look nice and friendly, but in reality its from more and more developing its own ways of murder, trying to invade the earth, leaving the blood of its enemies on the ground...
The profile picture is a Christmas tree, with several differently colored Yoshi's surrounding it. The green Yoshi with wings is flying on the top center, putting a star resembling a Super Star onto the Christmas tree. The blue Yoshi is standing in the bottom right corner, gazing with amazement at the aforementioned green Yoshi. The yellow Yoshi, in the bottom left corner, is also staring at the green Yoshi, although he looks slightly less amused. The purple Yoshi, also on the bottom left corner, is in the process of licking and possibly attempting to eat a Yoshi cookie, one of many used as decorations for the Christmas tree. And finally, the red Yoshi, located at the bottom center is glancing at Baby Mario and Baby Luigi, both also at the bottom center. Although we can't see them fully, they seem to be sitting on a pile of bags or boxes, possibly Christmas presents, as they seem to be preoccupied and not paying attention to the Yoshi's surrounding them.
The Christmas tree is rather grand, and is around the height of four to five Yoshis, hence why the winged green Yoshi needs to put the star on top of the tree. Although the bottom of the tree appears to be dark green, the color gradually fades to bright green at the top. The Christmas tree is littered with Yoshi cookies, which, as mentioned earlier, are used to decorate the Christmas tree. The designs of the cookies originate from the NES game Yoshi's Cookie, a puzzle game in which Mario, dressed as a chef, has to feed Yoshi cookies. The designs for the cookies are as such: a heart design, with a red substance, what a presume to be jelly, covering a majority of the cookie; a 2x2 checkerboard design, with two diagonal spots red, and the others plain;a square with rounded corners design with a red circle in the middle; a flower shape with a red circle in the center; a design which seems to resemble a three-leaf clover, and a couple of other designs which I am unable to identify from the profile picture alone.
The background is rather plain, with a solid white, accompanied by various shades of sky blue. Overall, the Yoshis seem to be enjoying their time spent together, and are in full festive spirit, along with Baby Mario and Baby Luigi.
the all-known goomba enemy presented in the mario games, but doesn't seem the same... he looks to be merged with a shroob, which is usually an alien that is toad-like, their appearance was first in mario and luigi: Partners in time. The similarity goes by its purple color and the difference in his eyes. He has two cyan feet, appears to possess a light green cap on top of his head.
It is a low-poly render of a snowman, more than likely from a video game from the mid-late 90s, as that was the general era of low-poly models due to the limited hardware of the time. The snowman doesn't look like the stereotypical three balls snowman and looks mean. They have a comically oversized top hat on with a large red 'x' on it, which is probably where you're intended to hit the snowman to defeat it.
The profile picture shown above depicts the character known as "Emily" from the television show which is titled "Thomas & Friends". Specifically, the avatar is focused on the face of the aforementioned character. The character appears to be happy and is looking toward her left. It is possible that she is reading the user's forum post and finding it enjoyable. Furthermore, there are small colored lights surrounding the character's face, in the colors of red, green, blue, and yellow. Most likely, they were placed here to celebrate the upcoming holiday known as "Christmas", as small colored lights such as these are a very popular decoration for the holiday.
