A gopher is an animal that burrows and often destroys crops. It has large external cheek pouches and is found in Central America and southwestern North America.
The idiom "Go for broke" means to risk everything in order to achieve the result you want.
So the title of this short film "Gopher broke" is a play on words as the gopher in the film is going for broke.
Mwahahaha. That video is a joy.
It's an extended metaphor of my life. 😉
