The former tennis player volunteered to tackle the Wash And Cry challenge, which involved finding items of clothing in a tub containing jungle pulp such as fish guts. When she discovered a token, she was required to crawl down a net and hang the item on a washing line.
"I volunteered for this - what was I thinking?" she asked Ant and Dec.
Martina found the first star on a pair of trousers as soon as the five minute time limit began. She then grabbed the second item, a top, and quickly hung it up. However, she struggled to find a third star and ran out of time.
Upon her return to camp, Martina said that she was disappointed to have only won two meals for the group.
Former Dollar singer David Van Day told the Bush Telegraph that he felt the same way. "I thought she would have done better than that, thought she was our jungle Jane. Two stars. Should have sent me," he said.
