Like many other cartoon characters, SpongeBob has been shown to have many remarkable capabilities and attributes for the series. Because the body is soft, supple, he was able to shape shift, have some level of immunity, capable of absorbing all kinds of physical effects, shown especially in the episode "The Bully". In episodes such as "Graveyard Shift", shows that he can quickly regenerate body parts injured or removed. SpongeBob is usually proven boneless (sea sponges are invertebrates were), but has been shown to have a framework in various episodes. As a sponge, he is also absorbent, and can expand his body to absorb the liquid, as shown in episodes such as "Culture Shock", "Gary Takes a Bath", "Squirrel Jokes" and "Dear Vikings". When he cries, he often re-absorb her tears. Despite having great abilities, SpongeBob displayed very weak physically, he used a stuffed animal as a "burden" in his private practice room, and in "Ripped Pants", he had trouble lifting a small wooden branch with marshmallows on the ends. The disadvantage is expressed also in the episode "MuscleBob BuffPants", in which he was not able to lift any object that is very light even as he fills "sleeve anchor" it in the air. However, like many aspects of the show, his strength is not consistent between episodes, and he has proven to have enormous power on various occasions, notably in "The Fry Cook Games", in which he has a very muscular body when he fights with Patrick.
SpongeBob also has some mastery of karate, but it is always different in each episode. In some episodes, he is shown to be very skilled, able to match or even beat Sandy on several occasions. However, in most of the series, he shows just messing around with karate, because he was usually beaten by Sandy.
Although usually seen (at least by Squidward) very childish and stupid, SpongeBob has proven to be very talented in many areas, and even sometimes have super-human intelligence. In fact, driving a boat is one of the few things that if SpongeBob doing will be not good. When he puts his mind to the task, he can achieve something, as in "SpongeHenge", where he spent the time to build a stone sculptures that produce sound that is identical to his voice, only to lure the jellyfish away. Thanks to the imagination, SpongeBob episodes have proven superior to Squidward in the arts, especially in the "Unknown Artist", in which he could produce a perfect statue of Michelangelo's David. In "Squid's Visit", SpongeBob really make an exact replica of Squidward's house from the rooms to the parts that are sometimes unexpected, even a replica of the painting Squidward Squidward recognized better than homemade. SpongeBob also has extensive knowledge of the subjects he likes, such as hunting jellyfish, Krabby Patty, and their history, and others. In episodes such as "Ripped Pants," "The SpongeBob SquarePants Movie" and, especially, "Band Geeks", SpongeBob display has a fantastic singing voice. He uses his nose as a flute, and always good voice.
