Sickly Sweet (The Grim Adventures of Billy & Mandy)

Sickly Sweet is the 67th episode of the The Grim Adventures of Billy & Mandy.

Plot
After getting tired of Mandy bossing them around, Grim makes Billy put the Mask of the Beast on Mandy, which causes her to turn into a monster whenever she acts mean. But in order to get the mask off and not transform into the beast, Mandy must act nice towards Grim and Billy.

Sour Qualities

 * 1) This episode is a bit of a Mandy Torture episode. She is a jerk of course, but does she really deserve that?
 * 2) Grim, Billy, and Mandy all almost act out of character. Yeah, Mandy needs to be nicer, but it comes off as hypocritical of Billy and Grim when they act obnoxious and taunting about it.
 * 3) The design of the beast that Mandy transforms into is bizarrely disgusting.
 * 4) There was one scene where Grim and Billy wanted Mandy to give them a sponge bath, which can be really uncomfortable?
 * 5) The face Mandy makes when getting annoyed with Billy is pretty disturbing.
 * 6) Unpleasant Ending: Grim and Billy gets tied up and Mandy (who is now fully transformed into a beast) starts kicking two of them repeatedly, feeling it was "worth it".

Sweet Qualities

 * 1) Billy can be funny at times.
 * 2) The concept of a Mask turning you into a monster when not nice is kinda interesting.
 * 3) "Sorry about the chocolate."
