The Battle Cats - Romantic Highway
Much like Overachiever Central, hit the base lightly to spawn out the first set of bears. Then once you take out the first set of bears, wait for your cannon to recharge and hit the base again to spawn the second set of bears. C. Gross can hit the bears if you're lucky, though it's better to just wait and Cat Cannon them.
