Yoshi Topsy-Turvy is a Nintendo Game Boy Advance action-adventure game starring Yoshi in a tilt-controlled side-scrolling adventure. The game uses motion-based controls to rotate the world around Yoshi, making level movement and puzzle solving central to the experience.

• Cleaned, tested, and guaranteed to play. Authentic cartridge.
• Tilt control affects the environment, letting Yoshi knock over enemies, swing pendulums, run up walls, and clear large gaps.
• Yoshi’s Island is trapped inside a pop-up book, with six chapters of courses to complete.
• Yoshi can transform into forms such as a ship, bouncing ball, and balloon to handle different chapter challenges.
• Course objectives include collecting coins, defeating enemies, and racing to the finish.

Bowser appears at the end of the adventure, tying the tilt-based stages back to the larger Yoshi and Mario universe.
