Their daddy is naughty. Sometimes Billy cries because of him. Mummy fish is very kind. Whenever daddy bothers Gilly and Billy, she would stop daddy.
One day, Mr Bill (their owner) had bought some weird-looking cave or something. He put it in the middle of the tank. Gilly and Billy was first to go inside the cave.
Inside the cave, it was dark, it was scary, but Gilly wasn't scared. She told Billy that she was big now. It was a really big cave. Soon, there was two different tunnels. Gilly told Billy that they were going to have to split up. Billy bravely nodded.
Both Gilly and Billy were scared. They were now on their own. Soon the two tunnels met up! Gilly and Billy were happy to meet again. They went through the tunnel together and soon, they saw light!
As they came closer, they saw mummy and daddy at the opening. Mummy was first to ask a question. She asked, "Was the cave scary guys?". Gilly and Billy both said at the same time "Yes!"
