The partnership is due to launch with two Lottie titles in May 2017.
Penguin Random House Children's has signed a deal to become the worldwide publishing partner for Arklu's Lottie Dolls.
The Penguin Random House Rights team will showcase initial plans for the Lottie Dolls books at the Frankfurt International Book Fair thismonth.
The partnership is due to launch with two titles in May 2017; one being a fiction title for young readers, and one a sticker dolly dressing book, which will be focused on stargazing and space.
A further two titles will then follow in September 2017 – again, one fiction, one activity book (format/concept to be confirmed).
"We are delighted to be the publishing partner for Lottie Dolls," said Leanne Gill, publisher of licensed properties at Penguin Random House Children’s.
"At Penguin Children's, we, of course, share Lottie's love of reading, but also her passion for inspiring exploration, creativity and individuality and a desire to promote positive role models for children. We can't wait to bring Lottie to a wider audience through our fiction and activity books launching in summer 2017."
Ian Harkin, managing director and co-founder of Arklu, added: “Our vision of childhood is simple, we dream of a safe and uncomplicated place where kids can be kids, where the great outdoors is there to be explored, where curiosity-led discoveries and imagination run wild and where the only limit is bedtime.
"Childhood should be an inclusive place for every girl and boy, and our publishing deal with the Puffin imprint at Penguin will be a perfect extension of our message. We are delighted to be in the company of much-loved authors such as Roald Dahl, Jeff Kinney (Diary of a Wimpy Kid) and Jacqueline Wilson, and are excited to announce our partnership with the enthusiastic team at Penguin.”
