At the Sky High library, they were looking up female superheroes. That's when they found a picture of a blonde heroine. They wondered who she was, so they walked up to Barnacle Boy, "Hi Mr. Kyles" Star whispered, "Who is this pretty lady?"
Lilo was impressed that Star was using an indoor voice for the library. "That's Captain Marvel" Barnacle Boy answered, "Real name: Carol Danvers"
"What's special about her?" Lec asked.
"She was a student at Sky High" Barnacle Boy answered.
Everyone was shocked by what Barnacle Boy said, they wanted to learn more about her, "After school, meet me in the Mermalair" Barnacle replied.
"Got it." The Celestian Alliance replied.
Later, they were in their mermaid forms, heading towards The Mermalair. "Too bad Stitch couldn't come," Lilo said,
"Where's your little alien friend?" Barnacle Boy asked.
"He hates swimming." Lec replied, "So we let him relax at the Booker Residents until we get back."
"I just hope my 2 brothers won't test him for their video games," Teal replied.
In a small box, there were numerous memories of Captain Marvel. Barnacle Boy explained that Mermaid Man has taught her everything he knew. Cho hoped that she didn't learn about Mermaid Man's forgetting habits. Barnacle Boy told them he didn't and decided to tell her origin story, "It all started back in the 90s." Barnacle Boy said.
