The Kinder Surprise Natoons range will be available from September in 20g (99p) and 60g (£2.56) packs, featuring 16 different animal toys to collect.
Each toy can be scanned to unlock a set of activities for children to complete on the app Applaydu.
The launch will be supported by a £3.2m media campaign including a TV advert, video-on-demand, digital and in-store activity.
A range of Natoons POS will also be available.
