Final answer:
The provided texts do not mention a Flowerground line with lizards playing sitars; the closest reference is of musicians playing other instruments.
Step-by-step explanation:
The question asks which Flowerground line had lizards playing sitars. None of the provided excerpts specifically mention a Flowerground line with lizards playing sitars. The texts reference various scenes and items, such as a lizard laughing outright at the idea of a red rose, a bird girl named Rima amidst colorful butterflies, and an incense burner, but there is no direct mention of lizards playing sitars in any Flowerground line within the provided materials. The closest reference to musicians is the description of a male musician playing the barbiton and street musicians with a guitar and violin. Therefore, based on the excerpts provided, we cannot confirm any Flowerground line featuring lizards playing sitars.
