This is an educational set to show off some basic care for reptiles but in LEGO form! Each cage has its own light bulbs and some have different sized cages to fit their needs. There is also an egg incubator to show how reptile eggs are hatched. The build is a small building with lots of plant life and animals around it like the alligator pond outside. Since Alligators need a lot of space the Reptile House includes a section of pond for the larger reptiles! This is a good build for anyone who enjoys reptiles in the wild or as pets or animals in general. I hope to earn your support!
