About Creator 3 in 1

Creator 3 in 1 sets come with instructions for three different models from the same bricks, built one at a time. The trick is in the design. Every part has to work in all three models, so the tiger of 31129 Majestic Tiger also builds a panda and a koi fish, and many builders keep the parts from a set as a starter supply of ordinary bricks.

3 in 1 was introduced in 2006 and currently consists of 252 sets. As of today, 4997 Transport Ferry is the most valuable 3 in 1 set with an estimated new/factory sealed value of $304.
