SpongeBob’s parents are both rounds like sea sponges, but why is he square like a kitchen sponge.
<|assistant|>
SpongeBob's parents may be round like sea sponges, but SpongeBob himself was shaped like a kitchen sponge due to the effects of the special magical jelly that is produced in the Mermaid Palace kitchen. When the jelly is poured into molds, it can take whatever shape the molds will hold. Since the molds of SpongeBob's shape had not been previously used, he came out square. Over time and through much experience and self-improvement, SpongeBob has been able to adjust his shape to fit more naturally within his surroundings. With a little practice, he was even able to make himself perfectly triangular for a short period of time. Eventually, however, his shape once again reverted to its natural, square form.
