My favorite part was when her father took Popcorn away because she was spending more time with her bike than with Popcorn.
I liked Radish, Jane, Popcorn, Sweet Pie, Kathleen and Grandma Aggie because they are in most of the story.
I liked the illustrations of Kathleen going fast because it is a little bit funny. Kathleen was trying to go fast but her teacher was trying to stop Kathleen and Popcorn.
I think that kids would read Birthday Pony because it's fun to read and there's pony's I love.
