La Giungla Tenebrosa is a 2D side-scrolling platform game starring characters from Kinder's line of chilled snacks, and one of four standalone Fresh Adventures games that each consist of a single themed level. Thieves have stolen a secret snack recipe, and Pinguì the penguin and Fetta al Latte cross a dark jungle to recover its six ingredients. You switch between the two heroes at any time: Pinguì jumps far and glides, while Fetta al Latte is strong enough to push obstacles aside. Snowballs freeze the parrots, snakes, and monkeys in your way, and the level ends in a boss fight against Dongo the gorilla.

Each of Kinder's chilled snacks is made from a secret recipe. When a band of villains steals the recipes, Pinguì the penguin and Fetta al Latte set out to get them back, guided by their friend Kinder Paradiso. In the dark jungle they must gather six ingredients (coconut, honey, flour, milk, chocolate, and sugar) and then defeat Dongo the gorilla, who is holding the recipe.
