Thu May 10 2018 19:56 All Aboard!: Arthur is completely obsessed with the Disneyland Railroad, and conductors, and Casey jr., and conductors. And also, conductors. He’s started saying “all aboard!” and waving his arm out like a Disneyland safety signal. Today he did it every single time he climbed onto the side of the grocery cart at Walmart. He was pretty loud, but it was pretty adorable.
