During the years sometime after Frank is transported to Cool World, he meets the doodle Lonette. While not much information regarding the history of their relationship is revealed, Frank and Lonette met and fell in love. They are in a serious and committed relationship, but they are unable to consummate their relationship due to the Cool World law that a doodle and noid are not allowed to have sexual intercourse. Aside from the law, their relationship is slightly strained as Frank is constantly on the job and has to be called away whenever they are on a date together.
In order to mend his relationship with Lonette, Frank asks his partner Snails to take on more responsibility while he temporarily leaves his duties as a detective to spend more quality time with Lonette.

Later as Frank begins his preparations to leave for the real world, Frank and Lonette walk together, soon sharing a hug goodbye before he departs. Later, after Frank manages to save Cool World, a deceased Frank and Snails return to Cool World and reunite with Lonette. Heartbroken, Lonette begins to grieve for Frank's death until she remembers another Cool World rule: when a doodle kills a noid in the real world, they are born again as a doodle.
