SpongeBob’s parents are both rounds like sea sponges, but why is he square like a kitchen sponge.

It is likely that SpongeBob was designed to be a square kitchen sponge because of his appearance in advertisements; a kitchen sponge is designed to be square so it can fit better on kitchen surfaces and hold more soap suds. This would explain why his parents are round like sea sponges.
