The most peaceful part of the Shee Ark is, predictably, home to the Norns. Also in this terrarium are doors to the Learning Room, the Graveyard, the Jungle Terrarium, and the Bridge.
The room features a bustling but somewhat unbalanced ecosystem. Food sources include apples, carrots and the seeds that fall from the tree, as well as a Cheese Machine in the lower level. Among the wildlife are Trout, Grazers, Gosh-hawks, Dragonflies, Ants, Bees, and numerous other critters. There are several places in the trees for birds to build nests, and there is also a pond.
The central Norn Terrarium
It also contains the Recycler that will recycle unneeded items, turning them into bioenergy for the ship, and a seed bank to replenish some of the flora and fauna of the Norn Terrarium.
The Incubator agent is located here for laying eggs, and it starts with the most toys of any terrarium: a Ball, Beatbox, Bongo Drums, Chopper Toy, and Space Toy.
