The Desert Terrarium rivals the Jungle Terrarium in unfriendliness - but where the jungle destroys a creature with hazards, the Desert Terrarium merely starves them to death. Due to the high temperatures and lack of food sources, the desert's ecosystem is alarmingly small, consisting of only a few hardy critters. Naturally, the lack of rain and presence of a volcano make the environment very hot and dry. Only a very few plants, like the Cacbana cactus and Desert Grass have adapted to the environment over time. However, Bramboo and Tubas grow quite well here. JayD created a Grape Vine agent, based on a C2 COB, to grow in this terrarium.
The feature that may make the Desert Terrarium stand out from the rest is the unusually large presence of machinery. Indeed, the terrarium is home to the industrious Ettin - due to their kleptomanic nature, the ettins regularly tromp around the SheeArk in search of machinery to hoard to their home.
