Now, where did I put that potion? I know it’s in here somewhere…
The wise and kindly Wizard has studied the magical arts for many years, and few are better than he at crafting spells, enchantments and useful elixirs. He knows just the right rhymes for undoing curses, and can cure hexes with a touch of his crystal-tipped staff. He’s even mapped out all of the dragon caves in the land so that everybody can avoid them.
But the Wizard’s problems began when he created his mystical Robes of Many Pockets. It sounded so useful to be able to carry his vast collection of potions, scrolls and spellbooks around with him all the time, but he forgot to write down the instructions, and now he can’t figure out what pockets hold what. When he reaches into one, he can’t predict whether he’ll pull out a rabbit, a wheelbarrow, or a hungry troll!
