Mo the Monster speaks English and Spanish! The Spanish mode was voiced by a popular Mexican actor Jaime Camil.
Regardless of the default language of their tablet, players will have the ability to select either English or Spanish by clicking the gear in the upper left hand corner of the screen. Both the language of Mo's voice and the language in the speech bubble can be selected in the settings.
For all other languages, only the "Asks" themselves (the words in the top right corner that Mo asks you to draw) are localized into your tablet's default language.
We plan to localize the Monster game into other languages besides English and Spanish in the future, and would be happy to send you an email once it's available in your language. Kindly fill out this suggestion form if interested.
