Rae was employed at the circus at the time when she met Benny, Leo, Johnny, and the Fantasy team. Also at that time, she became close friends with Mrs. Jumbo, who was expecting a baby, but the stork didn't show up. She allows the team to share the train car with her and Mrs. Jumbo and traveled on to the state of New York, around the time when the stork finally came and delivered a baby elephant named Jumbo Jr., but later adopted the name Dumbo.She is extremely upset when they locked Mrs. Jumbo up when she is just trying to protect Dumbo from being tormented by kids. When Timothy Mouse comes in to help and befriends Dumbo, the team come up with solutions to reunite Dumbo and his mother. Rafiki came along at the time and agrees to help out. They helped teaching Dumbo to fly and with Genie's help, they also flew with him. Later on, Dumbo becomes successful and reunites with his mother. Assuring that Mrs. Jumbo will no longer be lonely and depressed, she asked the team if she can join and becomes a faithful and compassionate team member.
In the latest adventures, Rae and the team stumble upon a magical brooch that transforms her into a magical warrior, giving her magical abilities to fight and heal. Rae will later proclaim Teresa as her second-in-command. She developed a friendly rivalry with Sunlight and has a grandfather-granddaughter relationship with Rafiki.
