I've had an idea for a new NPC species in Niche, and they would be quite the annoying ones.
The mockingshrike is a small bird, a mix of a Mockingbird and a Shrike. They would randomly imitate the sounds of other NPCs, such as a bearyna growling or a hawkowl crying, and possibly lure in said NPC- or just spook you. They could live in the thorns inside of swamp biomes, and your creatures could possibly find scraps of food impaled onto the spikes as shrikes do to their prey- and you would only be able to attack them when they're foraging on the ground.
Im bad at typing things l
