Rainforest

Lore & Background

In Planet Zoo, biomes are not merely backdrops; they are the ecological argument your zoo makes to the world. The Rainforest biome is the most visually dense of the options, layering ground-level ferns and bromeliads beneath a mid-storey of broadleaf trees and climbing vines, all crowned by a high canopy that filters the light into dappled green-gold shafts. Animated waterfalls tumble over mossy rock faces, and a soft mist drifts through the undergrowth, giving the space a living, breathing quality that no other biome in the game quite matches.

For players, the Rainforest is where the game's conservation messaging feels most tangible. The animals that thrive here—great apes, big cats, poison-dart frogs, tarantulas, birds of paradise—represent some of the most threatened species on Earth. Building their enclosures within this biome, with the right vegetation, water features, and hide spots, becomes a small act of advocacy: you are not just placing a cage, you are reconstructing a fragment of a habitat that is vanishing in the real world.

The biome also rewards creativity. Because the terrain and vegetation are so rich, players can carve gorges, build multi-level viewing platforms, and hide interactive elements like feeding stations or enrichment toys within the natural scenery. The result is an exhibit that feels less like a zoo and more like a window into a living forest, which is exactly the experience Frontier Developments set out to create.

In Their Own Story

The morning mist has not yet lifted when the first keeper steps onto the boardwalk. Below, the rainforest exhibit breathes: a slow, green exhalation of humidity that fogs the glass of the visitor gallery. Somewhere in the canopy, a howler monkey calls—a low, resonant groan that rolls across the treetops and makes the ferns shiver. A jaguar, half-hidden in the shade of a kapok tree, lifts its head, amber eyes catching the filtered light. The waterfall at the far end of the enclosure tumbles over its mossy ledge in a steady white ribbon, and the sound is so constant that the keeper has stopped hearing it altogether. She sets down a branch—enrichment, she calls it, though to the orangutan already swinging overhead it is simply Tuesday. The mist curls around her ankles. For a moment, the zoo is not a zoo. It is a forest, and she is only passing through.

Reader's Guide

The Rainforest is a full biome environment in Planet Zoo, available from the start of your park build. It provides pre-styled terrain with layered tropical vegetation, animated waterfalls, mist particles, and a warm, humid colour palette that distinguishes it sharply from the drier Savanna or the rocky Mountain biomes.

Its primary role is ecological: animals tagged with a tropical or subtropical habitat preference will register higher happiness when housed in this biome, making it the natural choice for parks focused on species like orangutans, jaguars, poison-dart frogs, tarantulas, and various tropical birds. You can also use it as a themed zone within a larger, mixed-biome zoo, which the game fully supports.

Why it matters: the Rainforest is the biome most players associate with Planet Zoo's visual identity. Its density of detail—swaying leaves, dripping water, volumetric light through the canopy—sets the tone for the game's core fantasy of building a living, breathing sanctuary. If you want your zoo to feel like a window into the real tropical world rather than a collection of separate cages, the Rainforest is where you begin.

Did You Know?

• The Rainforest biome features animated waterfalls and drifting mist particles that give the environment a dynamic, ever-shifting atmosphere unlike the more static look of other biomes.
• In Planet Zoo, each animal species has a habitat preference, and tropical species will show a visibly higher happiness indicator when their enclosure is built in the Rainforest biome rather than, say, the Savanna.
• The multi-layered vegetation in the Rainforest—ground cover, mid-storey shrubs, and high canopy—creates natural hiding spots and vertical space, encouraging players to design multi-level enclosures that mimic real forest
• Because the biome's dense canopy filters and scatters light, the in-game lighting in Rainforest areas has a distinctive dappled, green-gold quality that players often cite as the game's most atmospheric visual signature.
