Tiffi collected some lollipops from a nearby tree and recovers it.
Full list of appearances
Misty is a character in Candy Crush Saga. She is a unicorn first encountered in the 5th episode, Minty Meadow. She was crying because she had lost her horn. After completing level 65, Tiffi used a trampoline to take some lollipops from the nearby tree. This string became the recovered horn of the unicorn.
She is one of the few characters who appears in the 15th episode, Sweet Surprise after completing level 215. There is also a goof in her picture: her horn is missing.
She also makes a cameo in the episode Lollipop Lanterns, the 5th episode in the Dreamworld. There is no story that involves her, but she can be seen in the background, but with a dreamy palette-swap.
