Step into the backpack of Little Doug, a curious explorer wandering along streams and waterways. Lift rocks, observe habitats, and discover the tiny creatures that live beneath the surface. Each discovery reveals how macroinvertebrates help scientists understand water quality and ecosystem health.
Designed to encourage curiosity, careful observation, and respect for the natural world, the game mirrors how field scientists and environmental stewards learn directly from nature. Exploration comes first — learning follows naturally.
Each find offers a brief, real-world insight into the species you uncover, blending playful discovery with authentic ecological knowledge.
