Hocus and Pocus and the spell for home
(Book)

"Puppies Hocus and Pocus are ... waiting to be adopted from the Shelter for Slightly Magical Pets. Even though Hocus can see two minutes into the future and Pocus can turn bad feelings into bubbles (which he eats!), nobody seems to want them. This could be because the two keep causing mischief so they won't be separated. When Jinx the witch uses a 'spell for home' potion to help a color-changing tortoise find his match, the puppies know what to do: sneak both their hairs into the mixture to ensure they get adopted together. But with these two, anything can happen--from a shrinking spell to giant bees"--,Provided by publisher.
