Bunny was either an early nick-name or an earlier incarnation or possibly an alternate reality counterpart of Mary Ann Summers, the Kansas farm girl who ended up stranded on Gilligan's Island. She was a secretary, possibly from Los Angeles, who going on Mary Ann's back story, possibly won her trip to Hawaii, bringing along Ginger, a possible co-worker from her place of business. Not much else is known about her.
- Bunny was played by actress Nancy McCarthy; she would go on to be replaced by Mary Ann Summers, played by Dawn Wells.
- Bunny appears briefly in archive footage in Birds Gotta Fly, Fish Gotta Talk as a flashback.
