Baby seaponies don't have weights. For the water, just bring it to where the water just starts to bubble then lower the heat. The hair will be fine. This will actually alleviate a lot of the need for the cleaning products as well since most of the stuff inside will be loosened and you can you dish soap to get out the rest. I always boil all my ponies except glitter ones for obvious reasons. I've never had any trouble. Just be careful, and don't go full boil. I like to know my ponies will be safe for anyone (including little ones) to handle, since they could've been anywhere over 30 years of play or storage... ^-^
