軟爛

软 = 欠 + 车 : Rachel Rhinoceros (ru) left the anthill after drinking too much. When she got into her cabriolet (车), She felt that it was very soft (软), so soft in fact that she was not able to drive safely anymore: she drove her car directly into the anthill. Inside (an3) She then left an IOU note (欠) about the anthill's furniture for the owner of the anthill.

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).
