Ruins of the North is the fourth stage in Seeing Red.
- The boss, Dark Emperor Nyandam, appears at the start of the battle, followed closely by several One Horns and B.B.Bunnies.
- B.B.Bunny spawns in 1.7~3.3-second intervals throughout the battle.
- After 30 seconds, St. Pigge the 2nd appears with Pigge spawning in 20~30-second intervals. Up to five Pigges can be seen.
- Five Sir Seals spawn after 36.7 seconds. 10 seconds later, a Shy Boy spawns.
For the Timed Score Rewards, use a lineup that can quickly take care of the One Horns and reach Nyandam before the Shy Boy spawns. Ideally, you want to build up a large amount of attackers and interrupt Nyandam's attacks with knockback units to prevent him from killing your stack.
Lineup: Madam King, King Dragon Cat, Lion Cat (Combos: Three Kings, Lion King), Awakened Bahamut Cat, Jamiera Cat, Maximum the Fighter/Crazed Brave Cat, Elemental Duelist Cat, Dread Pirate Catley, Crazed Whale Cat, Island Cat
Begin by spawning your cheap attackers and upgrading worker cat a few times. The first One Horn that dies should fill your wallet, start sending out everything except A. Bahamut (and combo cats). Send Bahamut immediately after Nyandam attacks and hopefully the rest of the enemies will be cleared out quickly enough to pin him to the base before Shy Boy appears. Use Cat Cannon if Nyandam looks like he is about to attack. Note that in 3 star, Nyandam will kill A. Bahamut in 1 hit, so units that weaken red can help greatly if he manages to pull off an attack.
