红矮星

红 = 工 + 纟 : Mnemonic symbol: a little red book.

Helga Horse (hu) is reading the little red book (红) in the engine's kitchen ((e)ng2), when she discovers that it is being eaten by a silk worm (纟). She overreacts a little and wants to beat the silk worm with a steel beam (工).

矮 = 委 + 矢 : Albert Einstein (Ø) takes part in a darts (矢) tournament in the airplane (ai3), but the airplane's throne is just in the way of his darts, and he is too short (矮) to effectively throw the darts over the throne. Luckily he brought an artificial leg (委) which he can use to shoot the darts.

星 = 日 + 生 : The sun (日) and a satellite (星) had a love affair and now have a baby: Xi Shi (xi) is quietly sleeping in her little cradle (生) in front of the engine ((e)ng1).
