Experiment 323, known better by his nickname HunkaHunka, is a small, hummingbird-like alien that has the unusual ability to make any sapient being fall in love with another by pecking them with his beak. This is known to have unpredictible effects: in certain cases the subject might fall in love with inanimate objects or the opposite sex of a different species, sapient or not. The only "cure" is pouring or spraying the affected victim with water, which is likely due to the experiments apparently all (or mostly) sharing an extreme weakness to the substance.
