朽爛

朽 = 丂 + 木 : Marie Curie (xi) visits the outhouse (ou3) in late summer and finds an old rotten (朽) Christmas tree (木). In fact the tree is so rotten that she can't endure the smell and has to put on a breathing mask (丂).

烂 = 兰 + 火 : Sir Lancelot (l) is taking a bath in the anthill's bathroom (an4). The bathtub is sitting on a fire (火), so the water is really hot. Sir Lancelot has added a few orchids (兰) to the bath, but because the water is so warm, they're all mushy and rotten (烂).
