万儿八千

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.

儿 = 丿 + 乚 : Mnemonic symbol: "son" (儿) sounds similar to "Sun" like in "Sun Wu Kong", so it's gonna be represented by the monkey king. Albert Einstein (Ø-) and Sun Wu Kong (儿) are fighting in the space station's kitchen (-Ø2). Their weapons: Albert Einstein has a shovel (乚), and Sun Wu Kong has a banana (丿).

八 = 丿 + ㇏ : Mnemonic symbol: an eight-ball.

Beelzebub (b-) wants to find new ways to lure people into playing pool billiard. To this end he is meditating on top of an eight-ball (八) in front of the Ashram (a1). He uses a finger (㇏) and a banana (丿) as incense to create the right atmosphere.

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.
