Strategy 1 (Rush)[]

Immediately deploy a Can Can Cat. When it dances near the first Hippoe, deploy a Green Shell Cat, which should hit the enemy base. When Can Can Cat kills Hippoe and the money comes in, summon Awakened Bahamut Cat to destroy the base.

Strategy 2 (4 Crown Restrictions/Cheese)[]

Lineup: Riceball Cat 50, Courier Cat 50, Green Shell Cat 50, Cat Egg Pod 50, Awakened Bahamut Cat 50

Items: Rich Cat


  • The 5 "?" combos should be filled in with 2 Money UP (M) combos and 1 Accounting Power UP (Sm) combo. Better combos are advised for consistency, but not required.
  • Riceball Cat has the HP up MAX talent.

Immediately send out Cat Egg Pod, followed shortly by Green Shell Cat. Cat Egg Pod should kill off Hippoe, and Green Shell Cat hits the base. Save up for Awakened Bahamut Cat, and then send him out. Afterwards, send out one Courier Cat, then keep spamming Riceball Cat, sending out Courier Cat whenever you can afford it. The base should crumble as the Hippoe variants start pushing you away from the base.


  • Undertow Coast's Japanese name, Ōshio no Nagisa (大潮の渚, "Spring Tide Shore"), may be a pun on the late film director and screenwriter Nagisa Oshima (大島 渚), known as Ōshima Nagisa in Japanese.
