These are unused yellow Burgeoning Spiderwort berries I restored in Pikmin 2. As you can see at the end of the video, they used to crash the game when the Pikmin brought them to the ship. I've recently circumvented this by adding the last two lines of each of the codes. These codes make it so that the x #実タイプ parameter in the Burgeoning Spiderworts generators, when set to 2 will load the unused yellow berries, and when set to anything higher, will load mixed.
