Communication Icon

are a set of panels on the bottom screen of the Nintendo 3DS found in.

Overview
As their name implies, NaN Communication Icons are used to communicate between TFH: to express needs or emotions. When tapped, NaN Communication Icons appear on the top screen. With repeated tapping, the NaN Communication Icons grow to take a larger portion of the screen, allowing for them to be stressed. Different sounds will also chime depending on which Icon has been pressed.

The roster of available NaN Communication Icons sometimes changes depending on the TFH:' location. For instance, while waiting in the multiplayer lobby in TFH:, NaN Communication Icons reading "Hello!" and "Let's Go!" can be used. Once the TFH: enter a TFH: in the TFH:, more action-oriented NaN Communication Icons such as "Over Here!" and commands to use an item or perform a TFH: become available for use. NaN Communication Icons are not present during TFH: battles.

The "Cheer" TFH: is the only Icon to have more than one image. If TFH: repeats the same Icon, the image of the cheering TFH: will be horizontally mirrored, making it seem like he has raised one arm and dropped the other. This giving the illusion that TFH: is really cheering when the Icon is pressed multiple times. Additionally, the apologetic TFH: differs between Japanese and localized versions, as the Japanese gesture for apologizing is more closely associated with praying in western cultures.

Development
During development, more Icons were planned to be included but were removed as having too many of them would make it harder to communicate. An Icon seller was also planned to be included, who would have sold Icons in exchange for NaN Rupees.

Two Icons were altered late in development, after Nintendo had already released their art assets. The "Thumbs Up" Icon was changed to show TFH: winking instead of closing both eyes, and his grin was slightly widened. The "Nooo!" Icon had TFH:'s lower eyelids further emphasized, and his upper row of teeth were removed. The original versions of both of these Icons appear in Nintendo Badge Arcade as obtainable badges.

Trivia

 * An unused TFH: featuring TFH: yawning is present in the game's data. TFH:'s appearance suggests it is from an early point in development.
 * The "Let's Go!" Icon from the E3 2015 build had a similar appearance.
