A feature that is akin to the Mystery Gift feature of Gold & Silver, Card Pop! exists outside of the main game, on the initial menu of the game. If you put two GameBoy Colors together and use the IR port, you will both receive two random cards. These cards can be any non-promotional card from any set, but there is a definite reason to do this. There are two cards which cannot be obtained in the game without using Card Pop! Both of them are un-numbered promotional cards. However, you can only Card Pop with a person once. The Venusaur will never appear due to a bug.

Note: This feature will not work on the Virtual Console release but does on Nintendo Swith Online
