Mrs. Which loved everything there was to love about being a witch.

 A good witch of course.

Casting spells, playing tricks, and of course making potions.  

The only thing she did not like was her caldron.  Every Time she put something in, it would leak out.

Mrs. Which tried every spell she could think of.

She tired a bat wing spell, No, that only the caldron leak faster.

She tried a lavender spell. That turned the cauldron a very light purple. Mrs. Which did not like any color other then black.

She tried a lightning spell. That made the still purple caldron glow.  Yet it continued to leaked.

She tried a tongue of newt spell, that made the caldron talk. It said in a snarl. "Stop casting spells! I have a hole in my side, and your spells make it ache". 

Mrs. Which looked and sure enough on the cauldron's left side near the bottom was a big hole, made worse by her constant spells.

Mrs Which sighed took out some duck tape and fixed the hole,

Then she tried a crow spell! and not only did it work but the caldron no longer was purple nor did it leak.

Mrs. Which was so happy she made dancing candy. 

To this very day the caldron does not leak But it still glows, and speaks its mind to whomever who is in the room.

However the dancing candy did not fare so well.  For they had been turned into candy corn, and it was after all Halloween.
