Keepin' things simple. More or less.

Okay, Big, I want you to use Hypnosis on Kirby. Then, use Hypnosis on Celeste followed by Dream Eater on her.

Anthony, let's go with two Dream Eaters on Kirby after he's put to sleep and then one Dream Eater on Celeste.

If either of your fat and fluffy foes wake up or fail to fall asleep... Big, I want you to use Psychic instead of Dream Eater. Anthony, your replacement move is Superpower. Keep your same targets, guys.

Big: Hypnosis (Ki) ~ Hypnosis (Ce) ~ Dream Eater (Ce) (sub: Psychic)
Anthony: Dream Eater (Ki) ~ Dream Eater (Ki) ~ Dream Eater (Ce) (sub: Superpower)
