The free attraction at Bluewater in Greenhithe runs until 31 May, with nine markers unlocking interactive scenes, challenges with Bitzer and photo opportunities.
Visitors who complete the trail receive a sticker, using the Fun with the Flock app and location code 1603 or a paper map from guest services.
Bluewater will also host May half-term family events, including Shaun appearances on 27 May and Aardman clay-modelling workshops on 28 and 29 May.
