From Bulbapedia, the community-driven Pokémon encyclopedia.
Harvest Time is the name of a Pokémon-based e-Reader application. It is a minigame featuring Aipom. Five cards are required to play the Harvest Time application: Furret, Aipom, Exeggcute, Paras and Tangela.
In Harvest Time, the player takes the role of an Aipom collecting fruit that falls from trees. The objective of the game is to collect all of the falling fruit. Occasionally, a Sunkern will fall from the tree, and if Aipom catches it, it will be stunned for a few seconds. If fruit falls to the ground without being caught, a Swinub will take it and eat it. The game ends when Swinub takes the fruit.
