Squishy, clingy, and a little too close for comfort, Mr. Sweet was a red leech that attached itself to Ms. Guillyflower’s chest, who was the founder and owner of a utopian city called Sweetville. As you can imagine, Ms. Guillyflower’s Utopia was pretty awful and caused a lot of damage and death among local residents. After the Doctor and his friends save the day, Mr. Sweet tries to scoot away to safety, only to be smashed to bits with a cane by Ms. Guillyflower’s daughter.

He was seen in The Crimson Horror.
