All Flower Locations in Chapter 3 of Yoshi and the Mysterious Book

Chapter 3: Seaside of Yoshi and the Mysterious Book is all about water Creatures and Discoveries. This chapter mixes fun with levels like the Smurfboard and slight frustration with levels like Ouchin.

Every stage in Yoshi and the Mysterious Book is named after the newly discovered Creature, which may differ from player to player because of the ability to name every Creature. This guide will use the default names of the creatures given by Mr. E. Some of the Smiley Flowers in this chapter can be easily missed, so you’ll need to keep an eye out.
