Now you can get some Skele-Gro for yourself. Except that it isn't actual potion. This drink bottle is in the haunting shape of a bottle of Skele-Gro potion, just like the one used to regrow the bone in Harry's arm.
But if it helps, drnking water is a great way to help all the nutrients in your body get to your bones and keep them nice and healthy. So it's still pretty magical! And yu can always add fresh fruit, cordial or a little extra something to make it even more magic.
