At a giant beachside mansion, Pikachu and some of its buddies decide to play a game of hide-and-seek. Pikachu is “it,” and it goes off in search of its friends. Meanwhile, Larvitar, sick of being all by itself, kicks a rock in anger. The rock hurtles through the air—and hits a lawnmower, turning it on and sending it tearing off after Pikachu and its friends! The group draws the lawnmower into a maze and even gets it into the water, but the lawnmower just keeps on chasing. The Pokémon build a road out of logs, hoping to get the lawnmower into a shack, but Psyduck trips and ruins the whole setup. How will the friends ever escape the lawnmower? This fantasy will have you on the edge of your seat!
Unfortunately the movie Pikachu's PikaBoo is not yet available on HBO Max.
