特工

特 = 寺 + 牛 : Tecumseh (t) has a very special (特) mount: In contrast to the other Indians he rides a bull (牛). Moreover, the bull is so special (特) that it meditates in front of the Buddhist shrine (寺) in the elevator's bathroom (e4) together with Tecumseh.

工 = 二 + 丨 : Mnemonic symbol: a steel beam, since 工 looks like the cross section of a steel beam.

Gitta Giraffe (gu) is working a shift in front of the engine ((e)ng1). Her job is to melt dinosaur bones (丨) so that they can be disposed off easily. To melt the bones, she is shorting a huge capacitor (二) with a steel beam (工) which consequently heats up to a bright glow. Using the glowing hot steel beam she can melt the dinosaur bone easily.
