When Sabrina and Harvey are nominated as the "cutest couple" at Westbridge High's Winter Ball, she finds the perfect dress for the dance in the Other Realm. However, when Sabrina discovers it is one size too small, she decides to take diet shakes made in the Other Realm. The business man uses a spell to make her look fat and she agrees to buy more shakes. The shakes eventually make Sabrina disappear; not until she learns an important lesson about body image can Sabrina rematerialize.
Uses of Magic
When Sabrina is invisible she runs downstairs to open the door for Harvey who is waiting outside, but when the door opens you can just see the hands outside that turned the knob to open the door.
