Using your Sea-Monkeys Ocean Treasure Set is easy. First, set up the aquarium with the included Ocean Treasure Scene. Then, use the #1 Water Purifier to treat the water in the aquarium. After that, add the #2 Instant Live Eggs. Wait for your Sea-Monkeys to hatch. Once they're hatched, use the feeding spoon to give them the #3 Growth Food as directed in the 16-page handbook. Use the aerating water pump regularly to keep the water oxygenated and your Sea-Monkeys energetic. Make sure to follow the instructions carefully to create the best environment for them. Remember, the aquarium comes in two fun colors. The set's dimensions are 14.5 x 20 x 5 centimeters. Note that the item is part of an assortment and styles are randomly selected at dispatch. If you have a preference, add a comment in your order notes. Each item is sold separately. If you want to be sure to get the item you want, visit your local Toyworld store.
