Wuwu & Co.

"It is the coldest winter in two thousand years. Wuwu and her friends in the forest have come to the Little Red House, to ask for your help ... "

You can read the story about Wuwu and her friends when your mobile device is lying down. When you pick it up, you are suddenly looking into the forest where the odd creatures live. Here you can experience Wuwu’s artful world, while you are using your device in various ways to help her friends. You could, for example, shake your device to get the snow off the tree, or shout into it to wake up the Everetts, or even use the camera to find colours in the real world in order to light up the darkness for Storm’s tango loving family.

Wuwu & Co. opens a magical window into the narrative. It's a charming story with surprising physical interactions. Step in books will teach children about the interaction between the physical and the digital world and connect the actual with the virtual.

Explore the five different worlds in the woods and the cosy Little Red House by picking up the iPad or iPhone and shift into the narrative space.

The Characters

Wuwu is a large bird, who lives at the beach. All she ever eats is ice cream and fish, but during the winter the ice cream shop is closed and a dangerous shark is lurking in the waters where she usually gets her fish. Row out with her and aim your iPad or iPhone at the shark to fire a harpoon that will scare it off.

Everett is unable to wake up her siblings. She is a pig-butterfly and her siblings, whose names are also Everett, are sleeping larvae, hanging in cocoons from a large tree known as The Secret Place. Navigate to each cluster of cocoons and shout into the microphone on the mobile device as loud as you can, to help Everett wake them up.

Thit Maya broke all of her four legs when trying to jump into the frozen lake. She and all of her little friends love juicy pine cones, but with Thit Maya's injury, she can't shake them down from the tree and her friends are too little to do it. You can help them by shaking your device to make the pine cones fall down from the tree.

Storm lives at Snow Lantern Field with his fourty uncles and aunts. They all love to dance tango, but during the winter it is very dark at Snow Lantern Field, and the whole family is afraid of the dark. You can help them light their lanterns by using the camera on the mobile device to find a yellow color.

Pruney the troll is deaf so he speaks very loudly. Most of the animals in the forest are afraid of him because of this. Since he lost his match box he hasn't been able to cook his food and is therefore starving. Navigate through the forest by tapping on the screen, to find Pruney's lost match box.


The concept for Wuwu & Co. was to push the boundaries between traditional storytelling and games. The idea was conceived in Denmark at Vallekilde Højskole BookJam back in late 2013. The BookJam is a kind of workshop, in which participants have 48 hours to come up with and develop ideas that expand and challenge the constraints of the traditional book medium. Authors, illustrators and developers would join forces during this time to make this happen. One of the groups in 2013 consisted of Tim Garbos (game developer), Merete Pryds Helle (author), Kamila Slocinska (illustrator) and Aksel Køie (designer and producer). This group created an early version of Wuwu & Co.

At this stage Wuwu & Co. was little more than a prototype, but after receiving funding from the Danish Arts Foundation for further development, we were finally able to develop this prototype into a finished product.

The story for Wuwu & Co. was originally written in Danish but has since been translated into English. The Danish version first launched for iPad on the AppStore on November 6 2014 and then the English version followed on December 21 2014. The iPhone version was launched globally on August 27 2015.

About Step In Books

Step In Books is a multi-award winning company that explores spatiality in relation to narratives. We make books on mobile devices that the reader can "step into". We work to further establish intuitive interaction in stories and in films, but Step In Books is already a new way of experiencing stories on mobile devices. By taking advantage of the unique features of tablets and phones, we are able to create a truly interactive way of telling stories. You still read your book, be it illustrated or text-only, but at any time you can "Step into" the story world. It creates an immersive reading experience. Our projects include Wuwu & Co. - a magical picture book, Mur - a step in book, Seven Minutes in the Warsaw Ghetto app, that is more like a step in movie, a concept we strive to elaborate further in the future.
