The plot might involve Roshan getting lost. His adoptive 'family' of animals then has to search for him. During this time, Roshan discovers new things about the ice age world on his own. He might come across a strange ice formation or a new type of animal that he's never seen before. When his friends find him, he has new knowledge to share with them.
Another idea is that Roshan starts to show unique abilities. Since he is a human in an animal - dominated world, he might have skills like building more complex shelters or using tools in a different way. This could lead to the animals being both amazed and a little bit scared at first. But eventually, they learn to work together with Roshan to make their lives better in the ice age.
Obviously, Manny the mammoth would be one of his main protectors. Manny is big and strong, and he has a kind heart. He would use his size to shield Roshan from any danger, like other large predators.
It could be about Roshan growing up in the Ice Age. Maybe it focuses on his first encounters with the different animals. For example, how he reacts when he sees Manny the mammoth for the first time. It might also explore his relationship with his family in this harsh, ice - age environment.
Well, Manny the mammoth could be a main character. He could be like a big brother figure to Roshan, protecting him from the various threats in the Ice Age. Diego the saber - tooth tiger could also be important. Maybe at first he seems menacing but then he warms up to Roshan and becomes his protector too.
Well, it could center around the baby Moeritherium being found by a group of early humans during the Ice Age. The humans, at first, are not sure what to do with it but then decide to protect it. As it grows, it forms a special bond with the humans, and together they face the challenges of the Ice Age, such as finding food and shelter in a world dominated by giant glaciers.
Well, perhaps in the fanfiction, baby gets lost and peaches sets out to find him. Along the way, peaches discovers more about the world outside her family's protection. She meets different characters who help or hinder her search for baby. In the end, when she finds baby, they both learn valuable lessons about courage and loyalty.
Maybe the human baby is a special child with some kind of unique ability. In the Ice Age setting, this ability could be related to communicating with animals. So the baby uses this power to bring different animal species together to form an alliance against a common threat, like a large flood or a group of extremely aggressive and territorial creatures.
A great 'Ice Age Baby Dinos' fanfiction might involve a baby dino with a special ability, like being able to communicate with other species. In the Ice Age, this baby dino uses its power to unite different groups of animals against a common threat, such as a large and dangerous predator. It becomes a hero among the animals.
One interesting plot could be that Naruto and his friends are transported to the Ice Age world. There, they have to deal with the harsh environment and new, prehistoric creatures. Maybe Naruto tries to use his ninja skills to hunt for food or build shelters, but quickly realizes that his usual techniques need to be adapted to this new world. For example, his Rasengan might not be as effective against a woolly mammoth as it is against a human enemy.
Well, one possibility could be that the characters from Ice Age end up in the feudal Japan setting of Inuyasha. Sid could befriend Shippo, the fox demon. They might get into all sorts of comical situations together, like trying to find food in a world full of yokai. Manny, the mammoth, could be mistaken for a strange demon by some of the more superstitious villagers. And Diego might team up with Inuyasha to fight a common enemy, perhaps a powerful ice - based demon that threatens both their worlds.
A plot could involve a powerful jutsu in the Naruto universe accidentally creating a rift that leads to the Ice Age world. The Naruto characters then have to team up with the likes of Manny and Sid. For example, Sakura could use her medical ninjutsu to heal any injured animals. And in return, the Ice Age animals could show the Naruto gang how to survive in the harsh, cold environment.
