萬紫千紅

万 = 丆 + ㇆ : As mnemonic symbol I choose a neuron, since each neuron is said to connect to 10000 others.

万 = 丆 + ㇆ : Willy Walrus needs to dig up the floor in the anthill's bathroom, but he is tired of doing so manually with a plough. To make his life easier, he sets up a wind wheel for electricity, connects a neuron to the wind wheel and the plough to transmit the electricity and uses his new DIY electric plough to dig much faster.

紫 = 此 + 糸 : Zorro (z) needs some more special effects dust. To make it, he crushes a few amethysts (紫) in the space station (Ø3) by stomping on them with his boots (此). He then crafts a few bags out of a silken scarf (糸) to store the dust in.

千 = 丿 + 十 : Mnemonic symbol: a 1 kg weight.

The Queen of Hearts (qi) dropped a kilogram (千) on her banana (丿) in front of the anthill (an1), and now she uses a cross (十) to try and revive it.

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).
