Show us your mystery, deep within the darkness!

For their upcoming test, Mila, Conrad, Vicky, and Linus must explore the mysterious well that has stood in the middle of the forest for centuries. When they peer into the depths, they initially see nothing. But suddenly, colours appear, and the longer they look, the more outlines they make out. These must be the enchanted water gnomes! But which ones are they exactly?

Determined, they peer inside, because whoever finds out first wins the most golden coins!
