My Mini MixieQ’s is a line of tiny collectible characters that each offer “pop and swap” play. The My Mini MixieQ's toy figures can be customized with different headpieces and bodies. This enables kids to play with the collectible toys and create their own favorite figures rather than seek out one particular model. For the digital gameplay set to accompany this toy, we transposed this functionality to mobile and also introduced original game ideas around this unique feature.
