Wow really?
4 dragons total, and we get one habitat that holds 2. So either we pay 500g to house them all together, or squeeze 2 into other habitats, or buy the second one and try to make space for 2 habitats - and there's decorations that are never gonna fit anywhere. I always like having a bit of decoration out from the events near the dragons, but my island is so jammed now.
The colors look like they are all different - the lightning bolt new color, plus one other color, blue, pink, or yellow.
So whoever gets left out can't go together unless buying the 3 dragon one. Or use the 3 dragon instead of the 2, keep the 2 in storage, and find a home elsewhere for whoever is left out. Wow, 500g event... That's new.
