Well, Allen might try to pull the hand out forcefully. But this could have unexpected consequences like the door breaking open and releasing a horde of mini - ghosts. Then he'd have to deal with them while still trying to free his hand.
Perhaps Allen will realize that the door is a portal to another dimension. And the tiki ghost hand getting stuck is a sign that he's not supposed to go through yet. So he could start looking for a way to close the portal instead of just freeing the hand, which would lead to a whole different kind of adventure.
Another possibility is that a friendly ghost shows up. This ghost could tell Allen that the only way to free the hand is to make a sacrifice. Allen would then have to decide what he's willing to sacrifice. It could be something as simple as a treasured possession or something more complex like a part of his own power. This would create a great internal conflict for Allen in the fanfiction.
Allen could start panicking and call for help. His neighbors might come over, and they all end up having a big discussion about how to get the Tiki hand out. Some might suggest breaking the door, while others would be more cautious.
One possible plot could be that Allen is a curious character who was exploring an old haunted house. His tiki ghost hand, which has a mind of its own, reaches out to touch an ancient door. As it tries to pass through the door, it gets stuck. Allen then has to figure out a way to free it, perhaps by using some magic spells he learned from a local witch.
Maybe Allen will feel a sharp pain at first. Then he might start to panic and try to pull his tiki hand out. If he can't do it by himself, he'll probably call for help. Someone might come and try to carefully free his hand without causing more damage.
Perhaps in the fanfiction, the Tiki hand getting stuck is a sign of some sort of magic at work. Maybe the door is enchanted, and the only way to free the hand is to solve a riddle or perform a specific task. This could lead to an adventure for Allen as he tries to figure out how to free his hand.
There could be other characters involved too. For example, if it's set in a certain universe, other friends or allies of Allen could come to his aid. They might bring tools to try and pry the door open without hurting Allen further. Or they could call for help from someone more experienced in dealing with such situations. This kind of situation can also lead to some character development for Allen, as he has to deal with the pain and fear of having his hand stuck, and how he reacts to the attempts to free it can show his true nature.
Allen could first try to gently twist and turn his tiki hand to see if it can be freed. If that doesn't work, he may need to find some tools. For example, if there are any thin, flat objects like a spatula or a piece of thin metal, he could try to insert them between his hand and the door to create some space and then pull his hand out. Another option is if there are strong characters around, they could carefully pull the door apart just enough for Allen to remove his hand.
The story might progress with different characters having different ideas on how to free Allen's hand. Some might suggest brute force while others think of more gentle methods. As time passes, Allen could start to worry about long - term damage to his hand. Tikki could be the voice of reason, calming everyone down and coming up with a plan that combines different approaches.
