Sari is trying to convince someone to change without having to fight. As you can see, she has the ability to activate magical wings and that’s how she’s flying but when she’s not using them, she’s just a plain normal Unicorn.
 
 
Lyrics to the song:
 
I can make a promise  
I can make a plan  
I can make a difference  
I can take a stand
 
I can make an effort  
If I only understand  
That I  
I can make a change
 
You can make it different  
You can make it right  
You can make it better  
We don’t have to fight
 
You can make an effort  
Starting with tonight  
‘Cause you  
You can make a change

And yes, when I designed poneh Sari, I noticed that she has the same pallete or similar one to Babs Seed but she’s not Babs Seed.
