A Robanna is outgoing. Robannas are beautiful, clever, and irresistible once you become friends with one. Spongebob will run forever in a Robanna's veins, and tend to have a quirky and fun personality. If you are to remember one friend, it would be a Robanna, because Robannas are unforgettable.
Friend: Hey what do you want to watch?

Robanna: SPONGEBOB!! *Starts singing the F.U.N song*
