Divalettis are living ropes. Their biggest difference between them and snakes is that their head is in the center, which is not necessarily an advantage while trying to get around. Divalettis are always whining about everything and everyone. For the Divalettis it seems to be important to feel bad in order to be content. They pity themselves gladly during their imaginary illnesses. There would probably be no diseases on the planet would the Divalettis not constantly invent new ones.
