“I’m really happy with how HEY GRANDUDE! was received, as this was a very personal story for me, celebrating Grandudes everywhere and their relationships and adventures with their grandchildren,” said McCartney in the statement about the series inspired by the nickname the pop legend got from his eight grandchildren. “I love that it has become a book read to grandkids at bedtime all around the world. I always said if people liked the first book and there was an appetite for more, I would write some further adventures for Grandude—so he’s back and this time with his special invention, Grandude’s green submarine!”
Illustrator Durst added, “I am so thrilled to be collaborating with Paul again on Grandude’s Green Submarine. I think this is the adventure book we all need during this time, when everyone is stuck at home and longing to travel to exciting new places. I really enjoyed drawing the newest character in the book, Nandude, particularly because we both share a love of playing the accordion!”
