針線活

针 = 十 + 钅 : James II of England (zh) found a huge cross made from a bone and a flute (十) with a golden harpoon (钅) sticking in the bone in front of the encampment ((e)n1).

线 = 戋 + 纟 : Mnemonic symbol: barbed wire.

线 = 戋 + 纟 : The silk worm wants to use the floating tank in the anthill's bathroom, but there's already Marie Curie inside—and she secured the tank by setting up barbed wire all around it.

活 = 氵 + 舌 : Helga Horse joined the traditional water bottle challenge and empties a bottle of water over herself in the observatory's kitchen. To raise the difficulty level, she only uses her tongue to hold the bottle.
