It's Halloween and Lulu must decide on a costume. Should she be Ladybug Girl or something new? She tries different costume ideas, from a robot to a silent movie star to a vampire panda, but nothing seems right. Maybe she'll think of the perfect costume as she spends the day picking apples, going on a hayride, and navigating a corn maze. But it isn't until Lulu and Bingo help a little girl who is lost in the maze that, at last, she knows what she should be for Halloween - Ladybug Girl, of course! After all, she is Ladybug Girl, and it is important to just be yourself.
