This book makes the reader go Ahhhhhhhhhh.  An elephant has gotten lost and doesn’t remember anything, but the young kid Arthur becomes his friend.  They play and have fun, and eventually the elephant remembers just enough to contact his family who all come to help the elephant remember things and feel loved.  Within the illustrations one of the elephants that was called says Hi Dad, and another calls Grandpa.  This makes me think of alzheimers.  As a way to explain to kids that it is okay to get forgetful as you age.  Just help each other and things will be alright in the end.
