Flower routes and habitat counts were cross-checked against GAMES.GG’s Yoshi and the Mysterious Book Smiley Flower guide and rewritten in original TGGA wording. Exact screenshot captures still need to be replaced with matching gameplay screenshots where placeholders are shown.
When exact location screenshots are added, prefer The Gaming Guide Archives footage first, then small YouTube walkthrough channels with clear visible credit.

Should I clear the chapter in this order?
Use the Level / Habitat order above as a cleanup route, then revisit individual sections when a creature interaction or late-game tool makes a Flower easier to reach.
