Overview
Colorful Mayhem is a crossover event between Origami Bird Clash: Official Edition and Seal Slammers, offering upgraded multiplayer mechanics and fast-paced matches against other players. Participants can compete in two main modes, Double Seals and Best of the Flock, to earn ranking points and claim valuable prizes.
Double Seals Mode
The first minigame, Double Seals, reintroduces the familiar mechanics from Seal Slammers with a new twist. This time, each match allows players to deploy six baby seals instead of three.

Three seals will enter combat as your main Battle units, while the remaining three act as Assist seals, providing buffs and special effects to strengthen your front line. Victory is achieved by knocking out your opponent’s seals; reach six knockouts first to claim the win.
Teams can be customized around different seal types. For example, the Dark Seal Carry team focuses on pure offense, while the Red Hot Seal Carry team relies on combos and will-o’-wisp boosts for stronger attacks. Picking the right combination of seals and Enhancements like increased ATK or extra turns is key to dominating the arena.
Best of the Flock Mode
The second event mode, Best of the Flock, takes inspiration from Origami Bird Clash and introduces a new competitive ranking system. Each match features 30 players, and the goal is to boost your bird’s power by matching fruit tiles before time runs out.

Birds like Jadebird and Trailbirder are highly recommended thanks to their quick skill activation that requires only five matching fruits. Using Super Bombs or Cleansing Sprays on their respective fruits can trigger their abilities multiple times, making them ideal picks for those aiming to stay at the top of the rankings.
Failing to meet the required power level within each round results in elimination, so speed and precision are essential to survive the competition.
Gameplay Details
The Colorful Mayhem event revolves around two main steps: winning matches and leveling up through gameplay. Start by joining either Double Seals or Best of the Flock from the Multiplayer tab. Battle against other players, aim for high scores, and collect points to rank up.

The event’s gameplay encourages replaying both modes to master mechanics and experiment with different seal or bird setups. Even returning players can revisit guides for Seal Slammers and Origami Bird Clash to refresh their understanding of each system’s unique rhythm and strategy.
