From Bulbapedia, the community-driven Pokémon encyclopedia.
Sweet Scent (Japanese: あまいかおりにさそわれて) is the name of a Pokémon-based application for the e-Reader. It is a short cartoon featuring Vileplume. Only one card is required for the Sweet Scent application: the non-holo version of Vileplume.
There are two different versions of Sweet Scent. After the card is scanned, Version 1 will play, and when the application is replayed, Version 2 will be played. If the application is replayed subsequent times, this order will be repeated.
Vileplume is seen walking in the forest alone. It then uses the move Sweet Scent. Afterwards, a swarm of Beedrill will fly by, buzzing loudly. Then Vileplume will be left alone again, feeling sad.
