Cosmo is delighted when he passes the special test and becomes a witch-cat, just like his father Mephisto. Now he will be able to ride on broomsticks and help Sybil the witch with her spells - and it's all because of his magic sneeze, the all-important ingredient for Sybil's cauldron.

But Cosmo is one clever and curious kitty - and when scary Sybil starts cooking up a secret spell that produces golden statues his hackles are raised. Especially because the statues are in the shape of kittens . . . and look frighteningly ALIVE!
