MLBB Undersea Bash 2026: Friendship Coins, Free Rewards & Event Shop

The MLBB Undersea Bash 2026 event is now live and runs from November 11 to December 10, 2026, based on Server Time. Players can earn Friendship Coins, claim a free Plankton Battle Emote and exchange event currency for Aamon’s new Special skin and SpongeBob-themed effects. Undersea Bash itself does not require Diamonds.

if you also plan to enter the Bane “Mr. Krabs” collaboration draw, you can top up MLBB Diamonds on UUTOP after checking the price shown on your server.

Overview of event timing

Undersea Bash is the free-reward section of the returning MLBB × SpongeBob SquarePants collaboration. Its Event Shop closes earlier than the main skin draw, so players should pay attention to the separate deadlines.

All dates follow Server Time. Regional availability may differ, so use the countdown displayed in your in-game Event tab as the final reference.

How to Get Friendship Coins

Undersea Bash is the confirmed source of Friendship Coins in the 2026 event. Open the event page, complete the available activities and claim the coins before their missions expire.

The Undersea Restaurant minigame also returns during the same period. In its previous run, players prepared dishes, served customers and used Food Coins to improve the restaurant while earning Friendship Coins through event progress.

However, the official November notes do not publish the 2026 coin rates, daily limits or mission values. Check the live restaurant instructions before deciding how often you need to play.

To avoid missing rewards:

• Check Undersea Bash after each event reset.
• Complete time-limited and daily activities first.
• Claim finished missions manually.
• Review the Event Shop before spending Friendship Coins.
• Use all remaining coins before the shop closes on December 10.

How to Use Friendship Coins

After collecting Friendship Coins:

1. Open the MLBB × SpongeBob collaboration page.
2. Enter the Collaboration Event Shop.
3. Check each reward’s Friendship Coin requirement.
4. Prioritize the limited skin or effect you want most.
5. Confirm the exchange before December 10.

Do not wait until December 31. That is the closing date for the collaboration draw, not the Friendship Coin Event Shop.

MLBB Undersea Bash Rewards

Free Plankton Battle Emote

The Plankton collaboration Battle Emote is listed as a free Undersea Bash reward. Complete its required event objectives and claim it from the event page before December 10.

Aamon’s New Special Skin

Aamon’s new Special skin is available in the Collaboration Event Shop. It can be exchanged with Friendship Coins earned through event participation, so players do not need to obtain it from the paid SpongeBob draw.

The official announcement does not state how many Friendship Coins the skin requires. Use the amount shown in your live Event Shop rather than relying on leaked or Advance Server figures.

Collaboration Elimination and Spawn Effects

The Event Shop also includes SpongeBob-themed Elimination and Spawn Effects.

If Aamon’s skin is your main target, reserve enough Friendship Coins for the skin before exchanging coins for smaller cosmetic rewards. The exact priority depends on the prices displayed on your account.

Aurora Elite Skin

A separate event for Aurora’s new Elite skin begins on November 20 and ends on December 10. It belongs to the wider collaboration schedule but is not listed as a direct Undersea Bash Friendship Coin exchange.

Check the Aurora event page when it opens for its mission and claim requirements.

MLBB SpongeBob Collaboration Draw

The separate collaboration draw features three themed skins:

• Bane “Mr. Krabs” — new collaboration skin

• Cyclops “SpongeBob” — returning collaboration skin

• Gloo “Patrick” — returning collaboration skin

The first 10 draws guarantee one random permanent collaboration item. The guaranteed reward may be a skin, Recall Effect, Killing Notification or Battle Emote, so completing 10 draws does not guarantee Bane “Mr. Krabs.”

The first 10X draw receives a 30% discount, while the first 1X draw each day receives a 50% discount. Premium Supply is available from November 11 to 17, offering a free token from login and additional tokens through event tasks.

How Many Diamonds Does One Draw Cost?

At launch, available event coverage reports a regular single draw at 20 Diamonds, with the first 1X draw each day reduced to 10 Diamonds.

However, the Original Server announcement confirms the 50% daily discount without stating the numerical Diamond price. Players should therefore verify the amount displayed on their own server before drawing.

Can You Get Cyclops “SpongeBob” for Free?

Cyclops “SpongeBob” was obtainable with Friendship Coins during the previous collaboration, but the 2026 acquisition route is different.

The November 2026 Original Server notes list Cyclops with Bane “Mr. Krabs” and Gloo “Patrick” in the collaboration draw. The Event Shop announcement names Aamon’s new Special skin instead.

Unless Cyclops appears in the live Event Shop on your account, do not save Friendship Coins expecting to exchange them for the SpongeBob skin.

Best Way to Plan the Event

Use the free content before spending Diamonds:

1. Complete Undersea Bash activities.
2. Claim the Plankton Battle Emote.
3. Collect and budget Friendship Coins.
4. Secure your preferred Event Shop reward.
5. Claim the free Premium Supply token.
6. Use discounted draws only if you want a collaboration skin.
7. Check the live draw rules before committing more Diamonds.
8. This order prevents free tokens or Friendship Coins from being overlooked while keeping the paid draw separate from the free event rewards.

You can finish the free Undersea Bash missions, spend your Friendship Coins and use every available draw token before adding Diamonds to your budget. If Mr. Krabs or another returning skin is still calling your name after that, visit the UUTOP MLBB top-up page, select the amount you need and dive back into the collaboration draw.
