The challenge of the film was to create a realistic collection of 3D animals using CG animation and VFX. The animals included 3D pigs, 3D flying pigs and 3D chickens that sing along to a composed song.

The 3D animals had to be integrated into existing footage to match the look and feel of the live action footage captured of the "real" animals in Australian factory farms.

The flying pig had to be a photoreal, realistic and convincing version of a pig, so to not feel like a "cartoon".

The animals all had to capture the hearts of people as the plead their lot.
