The movie revolves around Bergens eating Trolls. It is not shown on screen, but is consistently referenced.
When the Trolls' lives are tossed into jeopardy becoming Trollstice food for the Bergens, they become depressed and worried, completely losing color and turning pale. The song "True Colors" is very emotional and beautiful.
One of the trolls is voiced by James Corden
A Bergen is briefly seen burying himself alive in a grave while singing a sarcastic sounding song although it's intended to be humorous some viewers may find it a little morbid.
The movie contains a scene showing a venus fly trap-like plant gobbling up surrounding small creatures.
