In Season 1 the Divers were Green, in Season 2 they are Yellow. That is the only way to tell them apart.
Right now, 2 LEGO Atlantis sets are sold every 46.3 seconds. That being said LEGO makes 40+ Dollars a minute just on Atlantis sets.
LEGO aimed Atlantis to target 8-12 year olds, but instead, people of all ages buy it!This theme is very good for LEGO Collectors. Mostly because in the making of Atlatis LEGO had to make 140+ new bricks. The pictures on the right are from the Atlantis Movie.
