Well, FanFiction.net has been around for a long time and has a vast amount of content. Look for the relevant categories or use the search function. Additionally, Tumblr sometimes has fanfiction snippets or links to longer works that combine Trolls and Watch Dogs.
Online platforms such as Amazon are great places to buy the 'trolls junior novel'. They have a large inventory, and you can often find both new and used copies. Plus, you can read reviews from other buyers to make sure it's the right book for you.
You can often find Trolls graphic novels at your local bookstore. Big chain bookstores usually have a section dedicated to children's or graphic novels where you might spot them. Also, libraries are a great place to look. They often carry a variety of graphic novels, including those related to Trolls.
You could start by looking on fanfic websites such as Archive of Our Own (AO3) or FanFiction.net. These platforms often have a large collection of fan - created works, including those related to Trolls.
They might get really excited and start comparing it to their own experiences in the Trolls world. Maybe they'll laugh at the funny parts or feel inspired by the creative interpretations in the fanfiction.
Another option is to check out Tumblr. There are often Tumblr blogs dedicated to Trolls and some of them might share or write their own Trolls Band Together fanfiction. You can search for relevant tags like #TrollsBandTogetherFanfiction to discover these stories.
You can try big bookstores like Barnes & Noble. They usually have a wide selection of graphic novels, including ones related to popular franchises like Dreamworks Trolls.
I would not recommend looking for'sick' fanfiction as it might involve disturbing or inappropriate content. But generally, if it exists in a proper and non - offensive form, it might be on some fanfiction websites like Archive of Our Own or FanFiction.net. However, make sure to abide by the rules and ethics of these platforms.
