Question (beginner) How can I play animations of multiple objects in a scene at the same time?

*I'm a 3DCG animator using Maya and just started learning Unity so don't understand basics...

There're a character and a balloon (produced by his nose) in a scene.
I made animations of the character and the balloon with Maya and exported them to FBX files.
In Unity scene, I added "animation" component to both the character and the balloon models and imported the animations, set them to animation components.
When I selected the character and play animation in "Animtion" tab, the character moves (sleep) but the balloon doesn't move.
When I selected the balloon and play animation in "Animtion" tab, the balloon moves (spread) but the character doesn't move.
How can I make them move at the same time?
I searched so hard but there's no answer on Google so please help me.
