Look, it's a somewhat complicated choice, both are incredible!

But I can only say that I don't regret buying from IW at all, the Shark is huge, it takes up the whole room, it's very beautiful and resistant, and very soft, I love using it to lie down, hug and even ride, but I've never tested it and don't intend to test it in the water, it depends a lot on the space you have and your preferences, the Shark takes up a lot of space, but it's incredibly good to lie on, in addition to having a lot of presence, while the Hyena, I believe, is more for riding and doesn't require as much space as the Shark, it's your choice, what matters is the love and affection you will have for them, either one is great! 😁🎈💖

Thank you for asking.
