针叶树

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). He wants to find out where it came from, so he uses a needle (针) to draw bone marrow from the bone to analyze its DNA, and it turns out that it once belonged to a white whale.

叶 = 十 + 口 : Maud Younger (y) practised a trick shot all day in the elevator's bathroom (e4). She's now able to throw a leaf (叶) high in the air, then quickly throw a mandarin (口) and beat the mandarin with a cross (十) like a baseball with a bat so that the mandarin rips a hole right into the leaf.

树 = 对 + 木 : Sheldon Shrimp cultivates a Christmas tree in the space station's bathroom. He is very happy that he found the right tree, just the one he imagined, and—in his mind—marks of the tree he imagined with a big green check mark.
