The official Pokémon movie website has updated. Translations follow:
Will Pikachu Be There With You? Or Will You Become Pikachu? Commemorative Movie Premiere SNOW Collaboration Stamps Make Their Debut!!
In order to commemorate the premiere of "Pocket Monsters the Movie: I Choose You!",
we're introducing stamps made in collaboration with the video communication app "SNOW"!
In the first set, we're releasing stamps that let you film yourself together with a Pikachu wearing Satoshi's hat,
as well as stamps that will let you transform into Pikachu or Nyarth!
You can see special actions by opening your mouth in specific ways.
Then, the second set, which has a stamp that lets you role-play Satoshi and reenact a scene from the movie, will be released Friday July 7th (scheduled date)!
These stamps are only available for a limited time, and are scheduled to be taken down Thursday August 31st.
