mushroom
🍄 mó gu sounds like more goo — soft squishy mushrooms; both chars carry the 艹 plant radical
蘑 (艹 grass + 麻 má) and 菇 (艹 grass + 姑 gū) both wear the grass radical on top, marking them as fungi/plants. The figurative senses pester and dawdle come from the slow, clingy way a mushroom-picker lingers.
