Diane slowly entered on the water of the lake.
She swimmed, shouting and trying to find her friend, Geraldine.
"Hello." Geraldine said.
"Gerald, I want to say how about you getting out of the water to explore the earth world?" Diane suggested.
"Just gimme a minute..." Geraldine said.
She picked a bubble and put on her head. She transformed her mermaid body into a normal bunny girl.
"Those are magic bubbles. They are filled with water." Geraldine said.
"We have this on the earth world too!" Diane said.
They explored the whole Underground, having fun.
