Using these Giant Grow Frogs is super easy. All you need to do is add water to the frog and then just wait patiently for it to grow. It's like having your own little science experiment at home. For kids aged 8 and up, this can be a really fun activity. When you receive the frogs, each one is neatly packed in a polybag with a header, so you can easily keep them safe. As for maintenance, just keep them in a clean and dry place when not in use. Avoid getting them dirty or damaged. Also, make sure to use clean water when making them grow. Have a great time with your new growing frogs!
