dodder (plant)
菟 centers on a parasitic plant: dodder, which twines around other plants. The meaning is narrow and botanical, without common abstract extensions.
菟 combines the grass radical 艹 with 兔, which likely contributes sound. The character is used for the dodder plant, but the exact historical development of this specific combination is uncertain.
The grass top 艹 over 兔 (rabbit) suggests a plant that tangles like a rabbit's warren: dodder, a parasitic vine that twists around other plants.
For ト, picture a dodder vine wrapping around a toe: toe -> ト, and the plant clings like a tangled vine.
