My daughter is obsessed with My Little Pony. 
oh the hasbro developed entertainment franchise
Yes, she loves them.  Her favorite is Apple Jack.  She likes the apple Cutie Mark.
The first My Little Pony was produced in 1981!
I wasn't even born then.  I think she also likes the Pegasus ponies. 
The ponies have colorful bodies and manes and symbols on their flanks
Aren't the symbols on their flanks called cutie marks, I think I mentioned the one on Apple Jack.
Yes the unique symbols are called "cutie marks"
They are so fun.  Their cartoons are very entertaining.
Since 1981 the ponies have been revamped to keep a modern look
