With a plan to tunnel past after the rains have run their courses
In keeping with the previous metaphors of plant growth as the act of creating meaningful hip-hop.
“Mosses” is also one vowel off from “masses”. Aes likes to do this as evidenced by Tetris references in “Tetra” + others. He is saying that he stayed underground, out of the mainstream, and under the masses even though he has the skill to be the most popular.
