Larrikins

Larrikins is a cancelled animated film from DreamWorks Animation. It was written by Harry Cripps and to be produced by Christina Steinberg. It was set to be released on February 16, 2018, before its cancellation was announced on March 5, 2017.

Plot
When an uptight bilby gets kicked out of the sheltered life of his family burrow, he ventures out and finds himself launched on a musical adventure across the mystical Australian outback. On the way, he must battle an evil army of monsters known as the Syvalionilas, or "Syvas" for short, and win the heart of his one true love.

Why It Was Cancelled
According to sources, it wasn't working out creatively. It had been pushed around the schedule and producer Gregg Taylor transitioned from his head of development job at DreamWorks Animation to work on the film. The project then made the move from Fox to Universal after the studio was acquired by NBC Universal. This constant change of workplace and schedule may have been the reason why it was shelved, along with The Croods 2.
