rachel bighead is ed and bev's transgender daughter, who was known as ralph in the original series. she was disowned by ed for not wanting to work for conglom-o, so she went to holl-o-wood to become a cartoonist. she created a cartoon called the fatheads (who are both voiced by charlie adler), a married couple with obese heads that constantly fight and hit each other with parking meters. "the fatheads" were based loosely on rachel's parents as a sort of retaliation for her awful childhood. rocko and his friends are big fans of the show. eventually, she became tired of being a cartoonist and wanted to quit to work on her true dream of building the world's largest still-life fruit sculpture, but was contractually obligated to keep producing cartoons for her company. in an attempt to get around this, rachel allowed rocko and his friends to create the show "wacky delly" assuming that it would immediately be cancelled and she could quit her job. instead, the show became a runaway hit, much to rachel's dismay. she then attempted to sabotage the show, but her attempts only made the show more popular. eventually, rocko convinced her that she should take pride in her work, which she did. ironically, her attempts to actually make the show good ended up getting it cancelled. years later, rachel finally created her art, the world's largest still life created out of rock; however, it only ended up reminding people about wacky delly, much to her horror.
