Well, focus on the friendship aspect. For example, the Bokoblin could be in trouble, like caught in a trap set by some other evil force in the Zelda world. Zelda comes across it and decides to help it out of compassion. Then, the Bokoblin could repay the favor later by guiding Zelda through a dangerous area it knows well. This way, it's about mutual help and not any inappropriate stuff.
To make it family - friendly, focus on the humorous side. For example, have the underwear be super - stretchy and make Ben do funny things like accidentally getting it stuck on a tree branch while chasing an alien. Avoid any inappropriate themes. Keep it about the wacky adventures that the underwear - related situation causes for Ben and his friends.
To make it family - friendly, focus on the adventure aspect. For example, if it's a story about a group of kids who get tied up by a bad guy in a pretend game, and then they use their teamwork to escape. Remove any violent or sexual undertones completely.
Family - friendly 'animal lemon fanfic' can be created by emphasizing positive values. Have the animals work together to solve a problem related to the lemon, like finding a way to share it equally. You can also add a touch of magic in a very innocent way, like the lemon having the power to make the forest more beautiful for a day. Keep the language simple and the story line straightforward so that kids can easily follow along.
Focus on the comical aspect. For example, have Robin play a prank on Batman by trying to tickle him while they are on a stakeout. Batman then pretends to be annoyed but secretly enjoys the light - hearted moment. Avoid any violent or overly suggestive themes.
By focusing on a sleep - over scenario. For example, Harry could be visiting a muggle friend as part of a cultural exchange program at Hogwarts. They stay up late talking, and then when they go to sleep, Harry might be a bit clumsy with some of the muggle sleeping arrangements like not knowing how to use an electric blanket properly. This would make it light - hearted and suitable for all ages.
You could turn it into a story about a girl who discovers that her burping has the power to make wishes come true (the 'wg' could be 'wish granting'). But instead of any inappropriate content, she uses this power to help her family. For example, she burps and a delicious meal appears for the whole family or she burps and a broken toy is fixed. It becomes a positive and family - centered story.
Add more elements of friendship and loyalty. Have Naruto introduce the Kyuubi to his friends in a positive light. They could all work together to face a common enemy. By doing so, it turns the fanfic into a story about unity and friendship, which is family - friendly.
A family - friendly 'Melody Pokemon tied up' fanfic can be created by making the reason for her being tied up humorous. Maybe she accidentally steps into a Pokemon's elaborate prank - like a web of ropes set up by a Spinarak. Then, the Pokemon that set up the 'trap' feels bad and helps her friends free her. Also, use colorful and positive descriptions of the Pokemon and the environment to create a warm and friendly atmosphere throughout the story.
One way is to focus on the emotional connection between them. Instead of the physical aspect, show how they support each other, like Vegeta being there for Bulma when she's facing a scientific challenge, and Bulma helping Vegeta deal with his Saiyan pride issues. You can also include their family moments with Trunks, showing a loving family unit.
Well, instead of a traditional pregnancy, it could be about a new life form being created in a very magical and innocent way. For example, a star falls in Neverland and implants some kind of magic in a character. Peter Pan and his friends then take care of this new magic as if it's a new life. It's like a pregnancy in the sense of nurturing something new.
