Casper & Nightmare #25

In "The Ghost of Many Faces," Spooky stumbles upon a magical formula that lets him transform into anyone he imagines—starting with Casper, then Wendy, and even a pig. When a passing witch catches him in his porcine form, she turns him into a football and takes him home, where his powers can't overcome her stronger magic.

In "Getting Unwitched," Spooky—still trapped in football form—finds himself handed to a witch’s children as a toy. When they accidentally break a window, the witch reverts him back to a pig, giving Spooky the opening he needs to reclaim his true self and make a break for freedom.
