<P> Voice recording sessions always include a full cast of actors, which Kenny describes as "getting more unusual". Kenny said, "That's another thing that's given SpongeBob its special feel . Everybody's in the same room, doing it old radio - show style . It's how the stuff we like was recorded". It takes about four hours to record an 11 - minute episode . For the first three seasons, Hillenburg and Drymon sat in on recording sessions at Nickelodeon Studios, and they directed the actors . In the fourth season, Andrea Romano took over the role as the voice director . Wednesday is recording day, the same schedule followed by the crew since 1999 . Casting supervisor Jennie Monica Hammond said, "I loved Wednesdays". </P> <P> The cast members get residuals every time the episodes they appeared in are aired, which Carolyn Lawrence described as "a very complicated mathematical calculation ." Lawrence said in 2008 that it was a "declining scale" and they were "still in negotiations...both sides are still talking ." She further stated that "they're still trying to work it out ." </P> <Table> <Tr> <Th> Actor </Th> <Th_colspan="2"> Character (s) </Th> </Tr> <Tr> <Td> Tom Kenny </Td> <Td> SpongeBob SquarePants </Td> <Td> Gary the Snail </Td> </Tr> <Tr> <Td> French Narrator </Td> <Td> Hans </Td> </Tr> <Tr> <Td> Patchy the Pirate </Td> <Td> Harold SquarePants </Td> </Tr> <Tr> <Td> Dirty Bubble </Td> <Td> Grandpa SquarePants </Td> </Tr> <Tr> <Td_colspan="2"> Other miscellaneous characters </Td> </Tr> <Tr> <Td> Clancy Brown </Td> <Td_colspan="2"> Mr. Krabs </Td> </Tr> <Tr> <Td_colspan="2"> Other miscellaneous characters </Td> </Tr> <Tr> <Td> Rodger Bumpass </Td> <Td_colspan="2"> Squidward Tentacles </Td> </Tr> <Tr> <Td_colspan="2"> Other miscellaneous characters </Td> </Tr> <Tr> <Td> Bill Fagerbakke </Td> <Td_colspan="2"> Patrick Star </Td> </Tr> <Tr> <Td_colspan="2"> Other miscellaneous characters </Td> </Tr> <Tr> <Td> Mr. Lawrence </Td> <Td> Plankton </Td> <Td> Potty the Parrot </Td> </Tr> <Tr> <Td> Realistic Fish Head </Td> <Td> Larry the Lobster </Td> </Tr> <Tr> <Td_colspan="2"> Other miscellaneous characters </Td> </Tr> <Tr> <Td> Jill Talley </Td> <Td_colspan="2"> Karen </Td> </Tr> <Tr> <Td_colspan="2"> Other miscellaneous characters </Td> </Tr> <Tr> <Td> Carolyn Lawrence </Td> <Td_colspan="2"> Sandy Cheeks </Td> </Tr> <Tr> <Td_colspan="2"> Other miscellaneous characters </Td> </Tr> <Tr> <Td> Mary Jo Catlett </Td> <Td_colspan="2"> Mrs. Puff </Td> </Tr> <Tr> <Td_colspan="2"> Other miscellaneous characters </Td> </Tr> <Tr> <Td> Lori Alan </Td> <Td_colspan="2"> Pearl </Td> </Tr> <Tr> <Td_colspan="2"> Other miscellaneous characters </Td> </Tr> </Table> <Tr> <Th> Actor </Th> <Th_colspan="2"> Character (s) </Th> </Tr>
