A Pygmy Marmoset is like a tiny, furry superhero with a very small cape that forgot to grow. Imagine a hamster that decided to swing through the trees instead of running on a wheel. It has a head that’s a bit too big for its body, eyes wide enough to make you think it’s always surprised by the world. Its fingers are like little twigs, perfect for climbing around but not great for holding a sandwich. And if you squint, it might remind you of a squirrel who accidentally took a shrink ray. Overall, it's a small bundle of energy that looks like it just chugged a double espresso.
