SVG for prompt ""Create a sprite sheet compatible with Unity in SVG format featuring a realistic pixel art guinea pig at a resolution of 64x64 pixels per frame. The sprite sheet should include four distinct animations, each with 4 frames: Walking: The guinea pig moves its legs and body slightly up and down to simulate a natural walking motion. Jumping: A smooth transition of the guinea pig squatting down, leaping into the air, and landing back down. Idle: Subtle breathing or tail flicking to indicate the guinea pig is alive and alert. Attack: The guinea pig lunges forward or performs a bite motion. Ensure that each frame is cleanly aligned for easy implementation in a Unity animation system. The art style should be pixel-perfect with a realistic guinea pig design while maintaining a readable and cute aesthetic.""
