Volume 4 of the 2.0 Update DIY's.    

Delivery via drop-off to your island. Due to the latest update, some DIY's cannot be flown with (e.g. Golden Axe). If this happens, don't worry. We will open our island instead and you can visit to learn all the DIY's before flying back.    

For a full list of included DIY's, see below.
