Im assuming your talking about Kotori? The code is: @keyframes float { 0% { transform: translateY(0); } 50% { transform: translateY(15px); } 100% { transform: translateY(0); } }

body:before { content: ''; position: fixed; bottom: 10px; left: 0px; width: 350px; height: 284px; background-image: url(https://file.garden/ZwSEZ6Dy7VYhtC14/tori.png); background-size: contain; background-repeat: no-repeat; z-index: 1000; pointer-events: none; animation: float 3s ease-in-out infinite; }

Just make sure that this code goes before any code that you have already :3
