As Ash and friends make camp on the way to Nimbasa City, they meet an unusual Beheeyem who offers (via Meowth’s translation) to make their wishes come true! Tired of camping in the woods, Cilan wishes for a good night’s sleep in the perfect hotel—and Beheeyem leads our heroes right to it! They settle in and quickly drift off...

...only to be awakened by Officer Jenny of the Psychic Crimes Division, who tells them that they’ve been trapped in a dream! They quickly chase down the culprit: it’s Beheeyem’s Trainer, Leon, who introduces himself as “the greatest Dream Thief of all time.” Officer Jenny figures out that as long as they’re trapped in the dream, they’ll have no power against the Dream Thief.

With the help of Officer Jenny’s Duosion and its psychic powers, they break out of the dream world—but it turns out that was a dream within a dream, because all of the party’s Pokémon are still asleep and dreaming. Ash, Iris, and Cilan manage to wake their Pokémon quickly, but Meowth proves to be more of a challenge. His persistent snoozing keeps them trapped in layer after layer of dreams, until Cilan finally gets the sleepy Pokémon to wake up with some super-spicy Figy Berries!

Decidedly not a “morning person,” Meowth is extra cranky at this treatment, and turns that frustration on Leon and Beheeyem, driving them away with a flurry of Fury Swipes. With the nightmare finally over, our heroes bid farewell to Officer Jenny and set off toward Nimbasa City once more.

But Jessie and James have beaten them there, and they’ve managed to divert one of the subway’s trains to a different route! The city’s two Subway Bosses discover this tampering, and prepare to deal with whatever happens next...
