Update: We now know the name of the mini-movies, Gunter Babysits, Love at First Sight, and Eddie's Life Coach. They appear with the DVD and Blu-ray release, though you can find them easily!
As usual, Sing will be available for purchase in DVD and Blu-ray form, though perhaps not in these few days - by the time they are available, I may watch the film - finally. And, just like other films by Illumination, there will be a/some mini-movies as well, but not even the names are known yet, however.
What's your idea about the possible plot of them? Comment!
