中缝

中 = 丨 + 口 : Mnemonic symbol: a dart board, because you always try to hit the center.

Julian Giant Squid (zhu-) is throwing dinosaur bones (丨) as darts on a dart board in front of the engine ((e)ng1). To make it a bit more difficult he's throwing mandarins (口) into the air as well and skewers them up right in the center (中 is a mandarin skewered on a dinosaur bone) in mid flight with the dinosaur bones. He's still able to consistently hit the center (中) of the dart board.

缝 = 纟 + 逢 : Frankenstein's Monster (f) is on a blind date (逢) with the silk worm (纟) in the engine's kitchen ((e)ng2). The date goes very smoothly, the silk worm even sews (缝) Frankenstein new underpants.

缝 = 纟 + 逢 : Frankenstein's Monster (f) is on a blind date (逢) with the silk worm (纟). In engine's bathroom ((e)ng4) he secretly inspects the panties the silk worm made for him and is amazed as he finds out that the panties are without any seams (缝).
