Purple berry



Purple berries are sweet, succulent berries found throughout the Fire Nation. Although harmless, they turn a person's tongue purple after being eaten and can cause a bellyache if too many are eaten.

History
Katara wanted to prolong Team Avatar's brief respite in Jang Hui in an attempt to aid the distressed villagers, but Sokka fiercely protested, as it would severely disrupt their tight time schedule. To force the team to stay, the young Waterbender secretly fed Appa purple berries, which stained his tongue a purple shade, causing him to appear sick; the group had no choice but to stay until the sky bison was better. Because of this, Katara was able to help the village at night while masked as the Painted Lady. Sokka discovered her trick when Toph accidentally ate some of the berries, which consequently dyed her tongue purple as well.

Momo seemed to have no objections to the side effects of the berries.
