Everytime the player completes a set (even if there are less than four Moshlings available in the set) the background of the habitat becomes colourful instead of yellow and dull. In the players room, there is a door that leads the player to the zoo if they have membership, there is also a way to the Zoo in the Moshling Garden. The Moshling Zoo door was updated on 28th March 2014, now in a circular shape beside the Missions button.
