Let It Grow is a meme probably inspired by We Are Number One. The meme began as a song in the Illumination Entertainment film ​The Lorax ​where the villagers of the town sing about wanting a plant to grow as the town currently has no plants or stuff. Then, near the beginning of 2017, YouTube user MrMangoHead (who helped give We Are Number One its popularity) uploaded remixes of the song in a similar fashion to the former. For example, "Let it grow but instead of grow it's die".
