Well, one common element is likely to be the initial 'kidnapping' situation which sets up the drama and tension. It could involve a character being taken by an antagonist or in some cases, by a character with good intentions but using wrong methods.
I'm not sure which specific 'kidnapped and tickled fanfiction' to recommend as it's a rather niche and not very common type. You could try searching on some specialized fanfiction websites like Archive of Our Own (AO3) where you might find relevant works.
Rather than creating a story about a girl being kidnapped and tickled, we could think of a story where a girl overcomes difficulties through positive means. For example, a girl participates in a friendly competition, faces challenges, and with her own efforts and the help of friends, she finally wins. This kind of story promotes positive values.
It's not okay at all. The idea of kidnapping is terrifying and adding something like tickling in that situation is inappropriate. We should aim to create stories that are full of love, friendship, and positive life lessons, rather than ones that involve immoral and illegal scenarios.
First, the boy should try to break free and run to a safe place if possible. If he can't, he should scream for help to attract the attention of people nearby.
Perhaps the kidnapper had a strange quirk where he would tickle the boy, thinking it was some form of odd 'bonding' during the time he held the boy captive. But this is a very abnormal and wrong behavior. Kidnapping is already a heinous act, and adding any such inappropriate behavior makes it even worse.
I'm not sure what specific story you're referring to with just 'a boy tickled and kidnapped'. There could be many fictional or real - life scenarios that might fit this description. It could be part of a mystery novel where a boy was tickled perhaps as a form of taunting before being kidnapped for some dark purpose like ransom or to use him in some illegal scheme.
One possible reason could be that it was a prank by some mischievous kids. They might have thought it would be funny to kidnap (in a not - so - serious way, like a pretend kidnapping) and then tickle the boy just for laughs.
A good Pokemon Dawn tickled fanfiction should stay true to the character of Dawn. Her determination and love for Pokemon should still be evident. Also, the tickling aspect should be written in a light - hearted and fun way, not in a way that makes it seem out of place or inappropriate in the Pokemon world.
First, develop interesting characters. Make the twins have distinct personalities. For example, one could be brave and impulsive while the other is more cautious and analytical. Then, create a tense and mysterious setting for the kidnapping. Maybe it's an abandoned warehouse on a stormy night. Also, build up the motivation of the kidnappers. Are they after ransom, revenge, or something else? This will keep readers engaged.
