Hypnotons

Hypnotons are substances that are found in space, and are used to counteract the effects of hypnowaves.

Dark matter is material that makes up for the rotation of galaxies. In s, dark matter is an exotic particle (particles that are made from more than just electrons, neutrons and protons). Nibblonians are the only known source but other sources could exist elsewhere. Nibblonians are probably made of exotic particles as they came 17 minutes before the Big Bang, which explains why their feces are exotic matter, moreover their long lifespans are able to accumulate such matter in their time.

History
In 3017, the Hypnotoad hypnotized Professor Hubert J. Farnsworth, making him order the Planet Express crew to take him to Amphibios 9. Once there, the Hypnotoad commenced his buzzing noise, making hypnowaves that revealed the female hypnotoad from a perpendicular universe.

The universe was pulled into the hypnowaves, but Lord Nibbler saved Philip J. Fry from being sucked in as well. They discovered the hypnotons while in space, and Nibbler surmised that they could be used to clear the hypnowaves. Fry worked with Nibbler, then later Professor Farnsworth and the rest of the inhabitants of New New York, to go on space missions to recover more hypnotons to restore Earth and the other planets in the universe.
