NEED MORE INVENTORY SPACE
Because of the changes that were made to the dungeons, we now have to collect 5 black birds, 5 yellow birds, 5 white birds, 5 red birds, and 5 blue birds. You need a full team of each color for the dungeons. That's 25 birds taking up precious inventory space. When the game first came out in August 2016, the dungeons didn't work that way. You didn't have to make space for 25 'dungeon birds'. You increased the requirements for the dungeons, now increase our inventory space past 100!
