Video prompt: A pair of otters playing and sliding down a muddy riverbank, splashing into the water with joy.
Defect: Deformation (any reason involved with a movement)
Explanation: The otter in the water appears to melt into its surroundings, exhibiting an unnatural and fluid-like deformation. Its body loses clear definition as it distorts and blurs, making its shape inconsistent and difficult to discern. This melting effect creates an unrealistic representation of the otter's physical form and movement.
