自掘墳墓

自 = 丶 + 目 : A hand mirror, which someone uses to look at her- or himself. The Eye of Providence is looking at itself in a handheld mirror in the space station's bathroom. It think it's indeed looking very good, since Zorro attached a petal leaf to its eyes.

掘 = 屈 + 扌 : Zeus (ju) heard that the elevator was built on the remains of an ancient civilization, so he plans to unearth (掘) any relics. He has quite high diopter (屈) though and so, unknowingly, with his toy claw (扌) he digs (掘) right below the pillars inside the entrance (e2), eventually leading to the collapse of the elevator.

坟 = 土 + 文 : Frankenstein's Monster (f) is digging its own grave (坟) right in the encampment's kitchen ((e)n2). While digging the grave it piles up a lot of dirt (土) which forms a small mound. Frankenstein's Monster plans to use a thick book (文) as a tombstone.

墓 = 土 + 莫 : After Mozart (莫) died, Malte Monkey (mu) built him a grave (墓) in the space station's bathroom (Ø4) out of clay (土). He even added a very fitting epitaph (墓).
