Hyaluronan Mountain (ヒアルロン山, Hiaruron Yama) is the last stage in Glucosamine Desert.
- Squire Rel appears as a peon.
- 3 Doge Darks appear as support.
- 3 Dagshunds together appear as the boss.
Save up money until you get your Cat Wallet at MAX Level. 3 Doge Darks will rush to the base, so use Cats that can deliver massive damage to Black enemies such us Weightlifter Cat or ranged attackers such as Dragon Cat to kill the Doge Darks. Following this, proceed to attack the enemy base.
When the Dagshunds appear, call in strong ranged units such as Bahamut Cat, and be sure protect them with meatshields. Having all the superior treasures, especially the Cat Health and Cat Attack Treasures, will help you win the level. A Valkyrie Cat (above Level 10) can also help with the level due to its relatively frequent attack.
