Extreme Earth: Landforms Adventure
Cross the wildest places on Earth.
This is not an ordinary geography kit.
Extreme Earth combines real specimen excavation, an interactive expedition story, an escape room, a scavenger hunt, a treasure hunt, collectible characters, trading cards, a map, and an online educational experience—all across the planet’s most incredible landforms.
Young explorers enter a massive wilderness filled with towering mountains, deep valleys, winding rivers, giant canyons, mysterious caves, islands, plains, and roaring waterfalls.
But the Grumblins have scattered the Gemlets across the landscape and blocked the expedition routes.
To rescue them, kids must follow the world map, choose their route, solve terrain challenges, search for clues, capture the Grumblins, and uncover real rocks, minerals, and fossils inside their Mystery Dig.
Every mission leads through a new environment and moves them closer to defeating the final Grumblie and rescuing all ten Gemlets.
Along the way, kids identify landforms, compare landscapes, investigate how they form, and explore how water, wind, ice, and Earth’s internal forces shape the world.
They are not simply looking at a map.
They are crossing Extreme Earth.

Their discoveries make the world beneath every landform feel real.

The Grumblins have hidden the Gemlets on mountains, inside caves, across islands, and deep within canyons.
