If you're running out of room for new decorations, you can rearrange the objects in the areas you've already unlocked.
- Try moving the habitats around. You might find better placements for them. 🐅
- Rearrange the pathways. Try avoiding crossroads to free up space for more decorations. 👣
- You can always store the decorations you don't need. Just tap and hold them and then tap the box icon in the pop-up menu. Don't worry, you can always get back any decoration you've stored. 📦
