Pikachu's Nighttime Adventure is a fantasy picture book. I bought my copy new.
Review:
Pikachu invites Eevee and Dedenne over for a sleepover. Eevee scares Dedenne into thinking ghosts are around, but thankfully the creepy thing outside the window turns out to just be Mimikyu. Mimikyu wants to go to the top of Dark Sky Mountain but is too scared to go alone, so the whole group goes together, experiencing a few frights along the way that turn out to just be other Pokemon.
I was charmed by Matsuo's first Pokemon picture book, so when I saw Gengar on the cover of this one, I knew I needed to read it too. This time around, readers are presented with multiple nighttime scenes, first too dark to see anything but ordinary rocks and plants and then lit up to reveal the Pokemon hiding everywhere.
