On the Kaiser Permanente float, 20,000 roses will show cat characters in a garden to promote healthy living. Ten children who have been battling childhood diseases will be riding on the float, including Shelby Markis of Brea, who was diagnosed with leukemia last year.
"I'm going to feel like a Disney princess, I've been practicing my little wave," she said with a laugh.
Despite her sickness, the 5 foot 2 inch teen has played as a guard on one of the top girls basketball teams in the nation, Brea High School. She said her coach said she was the spirit of the team.
"You just have to believe this has happened for a reason, and it's just going to make you stronger," she said.
Yajaira Gomez, who has been battling leukemia for the last two years, is another person who has been chosen to rise on the Kaiser float.
"When you hear the word cancer, the first things that pops into your head is death, so I thought I was going to die," she said.
On Monday, she was in good spirits, working on the float and practicing her parade wave.
