Super Zero/Sickly Sweet is one of my favourite episodes of the series as each of them provided the viewers with character development.
Super Zero wasn't so great but it was very funny. I liked the hydrogenated parts and I also was gross-laughing at Harold when he ate his brain! The only bad thing about this episode was that Grim was bullied by Harold, the old squirrel and Mandy.
Unlike The_Huntsman, I liked Sickly Sweet better and I think this is one of my favourite episodes. This episode provided us with the chraracter of Mandy and what she does everyday. She looked quite cute when she was the beast. The only bad parts were the parts when Billy and Grim were bullying her more than she does to them and I think the bath was going too far. Nevertheless, the ending was realistic and good and I liked it, it seemed Mandy wanted to be bad rather than sweet.
In the next episode about Mandy, "The Nerve", Mandy will have some character development again and we will see what makes her mean. "The Nerve" seems to be the sequel to "Sickly Sweet"
