New friends

So we just recently had some new neighbors move in, and they have a little girl that is just a couple months younger than Ethan. She is a cutie and Ethan really likes playing with her. He especially likes playing with her toys too. Here's a couple pictures of them on their motorbikes. It's funny, does something look out of place with these two? What's with the small pink bike Ethan? lol She's a lot braver than him too, when she see's bugs she tries to pick them up while Ethan is terrified of them. Opposites attract right?
