The Whole Cake Part 1 update is one of the biggest content expansions Grand Piece Online has received in a long time. It does not just add a new island — it introduces raid-style progression, new mythic fruits, new bosses, exclusive cosmetics, winter events, major balance changes, and long-needed system improvements.
GPO Whole Cake Island Update (Part 1) – Codes, Patch Notes
If you logged in and felt overwhelmed, this GPO Whole Cake Island Update guide walks you through everything that actually matters.
New Level Cap
The level cap has officially been raised to:
Level 675
If you were already maxed before, this update gives you room to grow again — and you’ll want every stat point for what’s coming next.
Whole Cake Island – New Main Island
Whole Cake Island is located between south and southwest of Rovo Island in Second Sea.
This island introduces an in-server raid tower that all progression revolves around.
Whole Cake Tower (Main Raid)
The tower has five total floors:
- 3 floors are puzzle / mini-game floors
- 2 floors are combat floors
- Every floor you clear solo grants you a unique title
- After all five floors are cleared, the Mirror World unlocks
A visual zipline appears that leads to the mirror room.
Entering the red mirror teleports you to the Mirror World, where you fight the Mochi Emperor.
Marshmallow Mini-Game (Free Global Buffs)
Whole Cake also introduces a global reward mini-game:
- Collect marshmallows from the chocolate river
- Stack them on the chocolate fountain
- When the server reaches its random stack goal, Big Mama eats the stack
- Everyone who participated gets to choose a reward
