With their expansive foliage, the new SIKUWORLD deciduous trees are easily integrated in the City (5501), Forest (5605) and Farmer (5601) sets. However, both of the mighty trees are capable of standing alone on their stable root system without the SIKUWORLD plates. In addition, the trunk can be extended, the foliage can be hidden and turned in different ways, and the crown of the tree can be used as a bush.
