The antagonist could be a dark force that has corrupted the snakes. In the fanfiction, this dark force might be trying to use the snakes to harm Sakura. It could be an ancient evil that has been awakened and sees Sakura as a threat to its plans. So it uses the snakes, which were originally neutral or even friendly, to try and get rid of her.
One possibility is that the snakes are under a spell. They wrap around Sakura because she has a certain energy or power that attracts them. In the fanfiction, this could lead to Sakura having to figure out why the snakes are drawn to her and how to break the spell on them. It could involve her using her medical ninjutsu skills or her inner strength that she has developed over time.

Of course, this was only a part of the dress. In many anime, every character had their own unique style of dressing.
I'm not aware of a specific fanfiction with that exact scenario. There are so many Starfire fanfictions out there that it would be hard to pinpoint one with this very specific plot point without doing a lot of searching.
In fanfiction, especially one involving Starfire, the mention of'red x wraps adhesive around' could be a very creative and unique plot device. 'Red X' could be a symbol, a character's alias, or even a new entity created by the fanfiction author. The 'adhesive' part is quite interesting as it gives a sense of something being stuck or bound. It could be used to create tension, like if Starfire is being restricted by this adhesive - wrapped situation. Maybe it's a part of a rescue mission where someone has to free Starfire from whatever the Red X has done with the adhesive, or it could be a prank within the story's universe.
The isolation of palm - filled areas can be a really scary element. In many of these stories, characters find themselves alone among the palms, cut off from the outside world. This makes them vulnerable to whatever unknown forces lurk there.
It depends on your tolerance for scary things. For some people who are easily spooked, they might find them very scary as ghost stories usually involve elements like the unknown and the supernatural.
There might be a story where a palm - filled island was once a place of dark magic. The palms were used in ancient rituals. Over time, those who visited the island without proper respect started experiencing terrifying hallucinations. They would see the palms turn into menacing creatures and chase them through the island.
