Zoo Basel in Switzerland is now home to two newborn baby Golden Lion Tamarins.
The baby twins were just born to parents Castor and Lilian.
Before that it had been 20 years since a Golden Lion Tamarin was born.
What's sweet is the father helps to raise the children as much as the mother.
The babies actually cling to the father some of the time.
We love their colors too!
Also, they're endangered, so it's so special every time one of these little guys is born.
And these were twins! Twice as good!
