Sweet Sue is a snail with black hair and a pink shell with a red swirl like Gary's Shell and it's female. She's next to the other female snail which is exactly like Snellie and Mary or Mrs. Puff's snail. She was seen in What If SpongeBob Was Gone? Shorts. When Gary is having a party with the others snails someone threw SpongeBob's stuff back in the house and Gary got hurt. Sweet Sue was only seen in the hit series "The Adventures Of Gary The Snail." She is the voice by Kelly Sheridan.
