LittleSausage

They're a warrior who found themselves caught by a snaretrap when they were a very young apprentice. While their clanmates attempted to rescue them, luckily having caught her foot rather than neck, a kindly twoleg happened by the whole scene and the patrol had no choice but to retreat to safety. The twoleg helped the apprentice to get free but then took them with because the apprentices' handpaw needed to be looked at and treated after it sustained damage from the snare. 

The twoleg patched them up and took great care to heal them to the point that the apprentice could walk again even if it was with a limp, the twoleg planned on keeping and having them fixed but before they could do so the apprentice escaped. Due to escaping before the leg was completely healed, the limp became permanent but it doesn't hold them back from being a skilled and determined warrior. 

They got their Suffix after the kind twoleg lovingly called them their brave little sausage, something about it stuck with LittleSausage amd so when they returned back to their clan they requested to be named LittleSausage once they earned their warrior name. The rest of the clan didn't get the name nor do they know what a sausage is but to reward the apprentices bravery and determination in making it back home again, the leader agreed. They then worked hard to become a warrior, turning their limp into a advantage rather than a misadvantage. They were named LittleSausage, as requested, alongside their peers and littermates.
