Blueberry Forest is the thirteenth level in Trine 4.
- Narrator: A fishy creature of the marshlands had surprised the heroes with her assistance. They had been given a vial containing a little bit of magic, but they didn’t yet know what to do with it. Following the Mermaid’s advice, Amadeus, Pontius and Zoya made their way to the Blueberry Forest.
- Zoya: Amadeus, can you tell us what’s in the vial?
- Amadeus: It’s some kind of a glowy liquid. Obviously magical. As for what it does… I haven’t the faintest idea.
