One popular one is 'So I'm a Spider, So What?'. It follows the story of a girl who is reincarnated as a spider in a dungeon. The novel details her struggles to survive and evolve in this new form.
The character development. In 'Reincarnated as a Slime', the slime protagonist starts from being a weak creature and gradually becomes a powerful and respected leader. We see his growth in terms of power, knowledge, and relationships, which is very engaging.
A well - known'reincarnated as an animal novel' is 'Mrs. Frisby and the Rats of NIMH'. In this story, Mrs. Frisby, a mouse, has to deal with the challenges of protecting her family. The rats in the story were part of an experiment and have gained intelligence. Another example is 'The Jungle Book' by Rudyard Kipling, which shows the life of Mowgli, a human boy raised by wolves in the jungle among other animals.
The novelty of seeing the world from an animal's perspective. For example, in 'Watership Down', we get to understand how rabbits view their world, their fears of predators and their search for a safe place. It's like entering a whole new world that we don't usually think about.
I'm not sure if it's extremely popular. It's a rather unique and strange concept for a light novel, and it might not have the mainstream appeal that more common themes like fantasy adventures or romances have.
I recommend you a novel called "I am really an animal doctor". It is a novel about urban life written by the author, Beiming Xuanyu. The protagonist of this novel had the ability to communicate with animals. After activating the animal medical system, he embarked on a path of no return to save cute pets. This novel is finished. I hope you like it. I hope you like my recommendation. Muah ~
A great 'Reincarnated as an Animal' story is the one where a character is reincarnated as a deer. In the forest, this deer had to learn how to avoid predators like wolves and bears. It had to find the best grazing spots and became part of a herd. The deer learned about the changing seasons and how to migrate to better areas during winter. Another instance could be reincarnation as a fish. Swimming freely in the ocean, exploring coral reefs, and escaping from bigger fish were the daily adventures. Well, these stories often explore the different natures and experiences of various animals.
It depends on your taste. If you like isekai (reincarnation in another world) stories, especially those with a non - human protagonist like a slime, then it's probably worth reading. It offers a fresh take on the genre with its own set of rules and concepts for the slime's abilities and growth.
The ending involves the main character achieving a high level of power and forging strong bonds with his companions. He overcomes various challenges and ultimately finds a place in the new world he was reincarnated into.
