The apple tree is an NFT that represents the whitelist for MyDuckly game. If you have an apple tree on your wallet, then you are on the whitelist. If you want to have more than one whitelist, you don't need to put an Apple Tree in each wallet, you can leave everything in one wallet, i.e. if you have 10 Apple Trees in your wallet, you will have the opportunity to mint 10x what is allowed for one whitelist.

        Within the MyDuckly game, the fruit of the Apple Tree also has value, it is an NFT that you can give to your Ducklys to recover energy and the rarity of your Apple Tree will directly impact on how much energy the fruit can recover.
