Make a story about a kangaroo and a Tasmanian devil. But not just any kangaroo and Tasmanian devil.
Alright, so your main setting should be in Australia since that's where kangaroos and Tasmanian devil live. Let's say something happened to Kangaroo. There was a deal between him and a dingo. Dingo demanded rabbits, rodents, birds, and/or lizards to eat for supper and would give Kangaroo something stylish in return. But since Kangaroo was a herbivore, he refused. Of course, Dingo got angry and told Kangaroo that if he didn't have any supper for Dingo by dawn, he would eat him.
Kangaroo, of course, couldn't do this alone. That's why he asked the Tasmanian devil if he could help. But what if this had a twist? What if the Tasmanian wasn't Kangaroo's friend, but instead, an enemy, perhaps?
Of course, Tasmanian would be skeptical. Why would an old enemy ask him for a favor? Kangaroo then explains and Tasmanian could offer to help. Soon, throughout a journey, you will see a bond start to form between Kangaroo and Tasmanian. Kangaroo teaches Tasmanian what he knows and vice versa.
Soon, when they spot a rabbit, it was Tasmanian's time to shine. But, this story needs some sort of conflict. What will happen if Tasmanian betrayed Kangaroo?
Maybe Tasmanian sneaks away and Kangaroo has no other choice but to get the rabbit. However, Kangaroo's style of thinking is different. He wants to find a way to make sure Dingo gets supper but also get his revenge on Tasmanian. Where does the story go beyond this point? It's now up to you.
This is just an idea, so feel free to edit out parts you want or add on parts you want.
