Rovia is a penguin brought to Bikini Bottom by his weapon. the hydra sword! He don't use it often so it its not seen in Bikini Bottom.
His personality is a brave and a bit insane person...
It sets up some freak outs. and it is friends with Sandy and SpongeBob.
he is known to be saving peoples lives every once and a while when the ocean is in trouble. Like Mermaid Man and Barnacle Boy.
