Welcome to Opal Nebula's lab. The study of creatures is as important as their care here. The walls have murals, each is a series of trees, grass nature, with a bubbling brook running through each, with each wall having a transition between the 4 seasons, winter with ice at the edges, autumn with various colored leaves floating down the brook and covering the ground, spring with crocus and other flowers and blossoms, new leaves and green grasses, summer with fewer flowers, and fruit in the trees. The animals are well cared for, and the equipment kept spotlessly clean.
