In this full game walkthrough and playthrough, I cover the complete Mario Tennis Fever Adventure Mode from start to finish with 100% no damage, presented as clean no commentary gameplay.
Adventure Mode begins with Mario and friends losing their tennis skills after being transformed into babies, leading Baby Mario to train at the Mushroom Tennis Academy and rebuild his abilities through structured lessons, drills, and story missions before the journey expands into later areas like the Airship, Ice Ruins, Limestone Cave, Dense Forest, Foggy Swamp, and the final showdown in the Valley of the Monsters. All NPC dialogue is included, so the story context, mission setup, and character interactions are fully shown throughout the playthrough.
This run is designed as a complete reference for everything the mode offers: a full route through every chapter and mission, all Mushroom Tennis Academy Drill-o-Matic minigames cleared on all difficulty levels, all Shot Ability stats fully maxed, focused EXP farming at the end of the Academy section, and endgame progression pushed all the way to Level 99 by the end of the Adventure. The entire walkthrough is completed without taking damage, keeping the gameplay consistent, precise, and fully optimized from the opening training to the final battle.
Thanks for watching and feel free to use this as a structured guide for your own Adventure Mode progression. Captured on Nintendo Switch 2 in crisp and smooth 4K quality.
