Once they all got to the shore, they looked into the water and saw the bleached corals.

Poppy said, "Oh, my. It's worse than I thought."

Trollex said, "It's moving so fast."

DJ said, "There's no time to lose! Helmets on, everyone!"

Everyone did just that and went into the water.

Although, when they started swimming, they saw Trollex was having a bit of trouble.

Poppy asked, "Are you ok?"

Trollex answered, "I'm fine. It's probably just the blanket. But, I shouldn't take it off."

DJ replied, "Here. Take my hand."

Trollex did just that and they were able to swim ok.

They all then raced ahead of the bleaching to Techno Reef.

When they made it, King Quincy shouted, "Everyone, take a blanket and place it on every bit of coral, and then put it on the highest setting!"

Everyone did just that.

They placed every cold blanket on every coral in Techno Reef.

Once they did, they set it to the coldest temperature on the setting.

They even remembered to cover the Heart of the Reef.

Once they were all done, they gave the spare blankets to the Techno Trolls to keep them cool.

Queen Essence said, "Be sure to cover your fins."

They all then saw that the bleach was upon them.

DJ said to Trollex, "You should probably head inside. It'll be cooler."

Trollex said, "Will you be ok?"

DJ said, "I think I'll be fine, but you and your people need to keep cool."

The other leaders looked at him and nodded in agreement.

Trollex then ordered his people into his LED castle.

Once every Techno Troll was inside, Trollex looked back at his friends and allies and gave them a look of encouragement.

He then went inside with everyone else.

TBDB then asked, "Do you really think this will work?"

Trollex answered, "There's only one way to find out. We just have to hope things will be ok."

Meanwhile, outside, King Quincy said, "Everyone, stand your ground."

Everyone did just that and held hands just as the bleach was just at the entrance.

It then happened.

The bleach had started going through Techno Reef.

It even covered the outside of the castle.

The Techno Trolls were able to keep cool, though.

Everyone outside shuddered as the bleach covered everything, turning it white and practically lifeless.

DJ looked at it especially with horror.

She then looked at her dolphin pendant Trollex gave her and suddenly felt herself full of hope.

It wasn't long before every coral in Techno Reef was white and lifeless.

Not long after, every coral in the ocean was bleached.

The Techno Trolls were able to look out the castle windows and watch with horror.
