About the game
Wonder Critter Lab is a relaxing creature synthesis game. Mix materials, create curious creatures, and watch them roam, chase, and eat one another to discover new species. Arrange them freely, try recipes, follow inspiration clues, and collect them all, with warm art and cheerful music.
Original Steam description
Wonder Critter Lab is a creature experimentation game centered on combining, observing, and collecting. Place different materials into the synthesis tray to create curious little creatures, then watch them meet on the experiment table—your next discovery might begin when one creature eats another.
Try combinations, create little creatures
Choose different materials and experiment with new combinations. Chicks, slimes, and fish come in all sorts of curious forms. Each experiment could bring a surprise—or a failed creation worth recording.
Watch encounters, discover new transformations
Creatures on the experiment table move, chase, and eat one another on their own. Drag them around to arrange an encounter, and see who eats whom—and what new creature might emerge.
Collect discoveries, uncover the creature guide
Record your experiment results in the creature guide, review the recipes you have discovered, and use inspiration clues to explore the unknown. Get to know the table’s curious creatures at your own pace.
