Seepa (adult male blue / female pink)
Fruit (Bush — grassland/wetland)
Suuba (Predator — hunts Seepas)
Siiba (hunts Suubas, eaten by Seepas)
How it works
- Seepas drink from ponds and eat fruit, apples, cactus flowers, pine cones and Siibas
- The map has four biomes — grassland (berry bushes & apple trees), forest (pines), desert (cacti) and wetland (extra ponds) — each with its own food
- Ponds, bushes and trees never overlap, and the map grows to fit your device
- All three species inherit speed and size genes that mutate each generation — natural selection in action!
- In spring, Seepas flock together — they align, group up and keep their distance like a real shoal (toggleable)
- Suubas are nocturnal: fierce hunters at night, sluggish and reluctant by day
- Siibas hide inside bushes and trees at night where predators can't reach them
- In winter creatures slowly freeze — they huddle near bushes and trees to stay warm. Bigger Seepas resist cold better, Suubas have thick hides
- Autumn is harvest season — leaves drift down and food grows fast and plentiful, so animals can fatten up
- Winter is harsh — snow falls and food becomes scarce (most berries and apples stay barren), so populations are tested
- Migration rescue (optional): a small flock wanders in if a species nearly dies out
