The Sandshifter Ruins are a maze of ancient structures and shifting sand. You'll need to solve a few environmental puzzles to progress. Look for switches that move platforms or reveal new paths. Some areas might require you to use a specific 'Thing' sticker to clear a blockage or activate a mechanism. Enemies here include stronger versions of Pokeys and other desert-dwelling foes.

Boss Battle: Tower Power Pokey
The Tower Power Pokey is a giant Pokey made of multiple segments. To defeat it, you'll need to systematically remove its segments. Jump stickers are effective for this, especially multi-hit ones. However, its head is spiky! You'll need to use a Thing Sticker to remove its spiky head. The Fan Thing Sticker (found in 2-3) is highly effective here, blowing away its head and making it vulnerable to Jump attacks. Once its head is gone, unleash your most powerful Jump stickers. Keep healing as necessary, as its body segments can still deal damage.
