Down in the deep deep sea, there was a pufferfish named Dr. Bubble. He had a lab to invent different things.

 One day Dr. Bubble decided to invent a robot that could clean the ocean because pollution there was becoming serious. He was worried that it would end up harming marine life*.

Marine life*= plants, animals, and other organisms that live in the saltwater of the sea or ocean

After trying and trying, Dr Bubble finally invented an AI cleaning robot. He called him Blubber. Blubber was like a whale so he could pretend to be a marine animal. The only difference between Blubber and a whale was that he ate rubbish. Blubber ate rubbish and broke them down with toxic* so there would be no more toxic. After eating rubbish, Blubber would be full of energy.

Toxic*=poisonous 

Blubber could do lots of things. When he saw a fish, he would know what kind of fish it was immediately. When Blubber saw Dr Bubble, he quickly surfed his data and knew that Dr Bubble was a puffer fish.

Blubber left Dr Bubble's lab and met some whales. He thought he looked like them! He asked,“Can I play with you?” Those whales also felt that Blubber was just like them, so they answered“OK”happily.

After playing for a while, Blubber and his friends were hungry. “Let's get some food”, said Whaley, one of Blubber's friends. They all swam to the shallow water and found some plankton. “Yummy!”smiled Sheba, another one of Blubber's friends.

 While Whaley and Sheba were eating plankton, Blubber found some rubbish to eat. He began eating some. “Mmm... It tastes good!”So he continued eating it. After finishing, he was full of energy.

Ha! Ha! Ha!

Ha! Ha! Eating rubbish !

Sheba saw Blubber eating rubbish and shouted “Blubber! What are you doing? Eating rubbish?” Whaley yelled “Blubber is crazy! He is eating rubbish!”All the fish thought Blubber was silly so they laughed at him!

Blubber was so sad as he didn't do anything wrong. He ate the rubbish to keep the ocean clean. But why did everybody laugh at him?
