SpongeBob’s parents are both rounds like sea sponges, but why is he square like a kitchen sponge.
<|assistant|>
SpongeBob's unique shape is a combination of traits from both of his parents. Since sea sponges are rounded, it is likely that he inherited his round body shape from them. However, since kitchen sponges are mostly square in shape, he might have gained his distinct four-sided shape from his parents, as well. Regardless, SpongeBob's square body and four-sided face give him an instantly recognizable look that sets him apart from other sea creatures.
