In this 100% walkthrough and playthrough, I cover Chapter 3: Seaside in Yoshi and the Mysterious Book as a full completion-focused no commentary gameplay showcase on Nintendo Switch 2.

Seaside continues Yoshi’s journey through the living pages of Mr. E’s encyclopedia, shifting the adventure into a coastal habitat built around exploration, creature interaction, and puzzle-solving across the chapter’s marine environments.

This video covers the full route through Chapter 3: Seaside, including the creatures Weewoo, Ouchin, Casterway, Bafloonder, Snurfboard, and Nep-Enut as a clean 100% run focused on collecting all Discoveries and Smiley Flowers for the chapter.

Captured on Nintendo Switch 2 in crisp and smooth 4K quality.
