LINE

 is a messaging app that is hugely popular in and other Asian countries. The service is known for its distinct stickers which can be sent with messages. Nintendo has used this service by creating three different series of stickers based on the Mario franchise, as well as an official automated account known as Kinopio-kun.

Mario franchise stickers
Nintendo has released three official sets of stickers for use with the app. Each set costs $1.99 on the app's store page. All of the stickers in each set are animated, and feature voice clips or soundbytes of the sticker's subject, which play automatically.

Talking Super Mario Animated Stickers
This was the first set released. The set contains 24 stickers based on characters from the Super Mario series.

Super Mario Bros. 8-Bit Stickers
This was the second set released. The set contains 24 stickers based on sprites from Super Mario Bros.

Mario Kart Stickers
This was the third set released. The set contains 24 stickers based on Mario Kart 8 and Mario Kart 8 Deluxe.

Kinopio-kun
Kinopio-kun is a Toad with a green-colored mushroom cap and a green vest. He is the mascot of Nintendo's LINE social media account. The account is an automated bot that will interact with messengers, depending on what they say to it. For example, if users text him the name of certain Nintendo characters, Kinopio-kun will respond with his opinions on said character. He makes it clear that he is not Toad himself, but rather a friend of him. His name derives from the Japanese name for Toad ("Kinopio") and the "-kun" part being a suffix used in Japan, usually to denote a man younger or the same age as the speaker.
