Zoo Tycoon 2: Extinct Research Lab

The Extinct Research Lab, as first seen in Zoo Tycoon 2: Extinct Animals (2007), though it's more well known due to Zoo Tycoon 2: Ultimate Collection (2008). This build contains 894 pieces, 3 Dodo birds, the illusive Killer Penguin, and 5 minifigures: 2 guests, a caveman employee, the scientist, and a paleontologist.

The Extinct Research Lab itself features a removable second half, opening doors, and two removable platforms: one of the fossil build room and another of the creation lab. These can be used to build and create new Dodo birds. The exhibit next to it features the Dodos themselves, with a pond, two rainforest trees from the games, dishes for water and berries, and a pursuit ball. The exhibit is modeled after the extinct themed objects, and has a working gate. The sidewalk itself is a separate side build, with a donation box and a gift cart. There is also a dig site and a fossil finder.
