Warriors: Hiding Within The Ferns

So when the four Clans reached their destination, they formed two Clans. WindClan and RiverClan formed RabbitClan. ThunderClan and ShadowClan formed SunClan. They lived in peace for many moons. But all changed when SunClan was accused of stealing four RabbitClan kits. SunClan claimed they didn't have the kits, but RabbitClan did not believe them. The two Clans were locked in battle for moons and moons. Though the kits were never found. Where are the four missing RabbitClan kits?
