Little Brush Big Brush AR Experience

Objective

Signal sought to transform toothbrushing habits in children by making daily dental care engaging and fun. The brand created an innovative digital experience that gamifies oral hygiene and turns brushing into an interactive daily ritual, targeting young users in key markets like Indonesia and Vietnam.

Solution

Signal launched a 21-day AR-powered chatbot companion on Facebook Messenger, built with Spark AR. The experience features collectible animal characters and an episodic narrative with 21 two-minute interactive episodes. Children advance through the story by completing daily brushing challenges, with visual rewards and character progression to motivate consistent dental habits. Created by MediaMonks, the experience represented one of the first AR games delivered via Facebook Messenger.
