They have their birthday in close days. Art's birthday is September 7th and Biro's 9th.
Of course they are my favorite characters, I love them as my own children.
Art is always happy when he's with his best friend Biro.
If you want to read his comic, don't miss a single page, each month I'm submitting a new page each month. Click this link: www.furaffinity.net/user/artbiro
