中子彈

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.

子 = 了 + 一 : Zorro wants to eat an egg in the space station, and he already put it in a prize cup, as he has no egg cup. He also lacks a spoon, so he uses a big flute to crush the egg open.

弹 = 单 + 弓 : Don Quixote (d) is preparing a bullet (弹) list in the anthill's bathroom (an4), but he took the term a little too literally. To create the bullet points on his list (单), he is trying to shoot bullets (弹) at the list using a composite bow (弓).

弹 = 单 + 弓 : Tecumseh (t) is giving a concert in the anthill's kitchen (an2). He is playing a composite bow (弓) with just a single string. As he is plucking (弹) the string (弹) of his bow, he often looks at the floor where he taped a list (单) of songs to play so that he doesn't forget which song is next.
