End of pixls

Saffron: Saffron is a chef in Flipside, she runs the Sweet Smiles Restaurant. She has a sweet personality, often calling the player in SPM "Sugar". She should have a sweet and Southern Accent

Red and Green: Two mustachioed brothers found in Yold Town

Shadoo: a being created by the Ancients found at the end of the Pit of 100 Trials who makes shadow copies of the heroes. Should sound Shadowy and mysterious

D-Man: The D-Men are found in the Underwhere and they work for Queen Jaydes, based on their looks I imagine they have serious business sounding voices, maybe a very slight New York accent as well.

Shayde: The Shadye are the souls of the dead, they reside in the Underwhere. They should sound ghostly

Nimbi's: Nimbi's are found in the Overthere, male and female voices, They should sound kind of heavenly.

Doorguy: DoorGuy 1, 2, and 3 are doors that reside in the Underwhere, they give the Heroes questions that they need to get correct in order to proceed, with Doorguy 3 making them fight the Underchomp. Their voice should be deep, but not overly deep

Old Ladies: In the Underwhere there are 3 Old ladies that will have the Heroes get something for them in exchange for a key.

Sammer Guys: The Sammer Guys should sound like Samurai Warriors, there are 100 of them but in the story you only encounter like 30-35 maybe

MeowMaids: These are cat robots in Fort Francis, They should sound cute and their voices should be a young female..... Nya~

Blumiere's Father: The Father of Blumiere/Count Bleck. He has a very Minor role only appearing in a couple of flashback/memory scenes, but he's still a very important character. His voice should be posh like Bleck's but have a certain wise tone to it, not too wise though as he did "get rid of" Timpani

Princess Mindy: King Neptune's Daughter, in this story she will reunite SpongeBob with the Golden Spatula that he pulled out of the grease in Season 1. Her voice should sound like a slightly older version of Scarlett Johansson's Voice for her
