Star Ocean is the last stage in Low Tide Beach.
Battleground
Doge and Those Guys appear as peons.
Doge Dark has a very unique appearance in this stage; it gets stronger as time passes by, so it appears as a constant threat.
H. Nah appears as a boss.
Strategies
This level is about area damage to take out the Doge Darks fast enough to get damage off on H. Nah. Valkyrie Cat is useful in this stage to take out the Doge Darks.
It is recommended to have as many Area Attackers as possible, such as Paris Cat, Crazed Sexy Legs Cat, Crazed UFO Cat, Drama Cats, Ring Girl Cat or Kasa Jizo to suppress the Doge Darks. Crazed Sexy Legs Cat helps a good deal amount in the beginning as it clears out the peons which in turn gives you money. Equipping a Cat CPU will greatly help if you cannot spawn your meatshields fast enough (Wall, Macho, Samba, etc.) Cat CPU will also help because of the infinite amount of doges that spawn and provide money.

Trivia
- On 3-star and 4-star, this level contains the strongest Doge Darks in the current version of the game. The Doges will eventually level up to have 120,000 HP; 48,000 DMG!
- However, when comparing 1-star difficulty, Valkyrie Plains has stronger Doge Darks. Due to the star nerf, 3-star Valkyrie Plains will have weaker Doge Darks than 3-star Star Ocean.
