Is Barney a boy? If he is, he is very charming. About 90% of girls (toddler) love him. And I believe some boys do love him as well. (Or she is a girl?) I am not sure.
For Yvette, she watch nothing about Barney. She only know two songs about Barney thru JGC and one from the ride.
She usually will be given one ride when we are in the mall, and she will choose Barney.
