Pikachu Lens available in Snapchat for limited time
A Pikachu Lens is available in Snapchat for three days. Pikachu's ears, nose, and bright-red cheeks will appear over a person's smiling face when using this Lens.
When using this Lens, if the subject opens their mouth, Pikachu will also appear in the photo and Pikachu will cry out as it jumps onto the screen and strikes a pose.
While English language announcements do not specify a specific duration, the Japanese Pokémon Twitter clarifies that the limited time is three days.
