Video prompt: a group of colorful baby koi fish swimming and trying to get food in a pond. The video is part of a series of clips capturing their playful and curious nature.
Defect: Deformation (any reason involved with a movement)
Explanation: The fish’s tail merges with the adjacent part of its body, blurring the boundary and creating an indistinct form. Additionally, its mouth undergoes a deformed, misshapen change, giving it an unnatural and distorted appearance.
