The LEGO Jungle series is one of my favorite series of sets that I have seen in a while. There are some great sets in this line. There are also a bunch of new big cats including a tiger, leopard and black jaguar. The vehicles are also a lot of fun. Andrew has the Half Track vehicle and when he picked out that set I picked up the set with this mini helicopter and ATV. The sets are also very conducive to imaginative play with treasure hunting and dangerous animals. Exploration and also dangerous plant life. Traps and treasures and more. There are so many things that you can do with these sets. I would like to get the larger sets for Andrew, if I can find them on sale.
