Patty was a Krabby Patty that was made by SpongeBob. It was a female Krabby Patty with whom SpongeBob fell in love with. SpongeBob never wanted to eat her because he loved her. She was only seen in the episode, "To Love a Patty." SpongeBob and Patty did lots of things together like dancing. SpongeBob also serenaded her with "Oh Baby."
Patty is a meat patty with tomato eyes, lettuce hair, cheese clothes, and ears and ketchup dimples. Her nose is made of a pickle and her smile is a squirt of mustard. As the episode goes on, Patty becomes more deteriorated. Green stench comes out of it and Patty is looked to be squashed and off color. When SpongeBob was singing to her, she fell in the water, which made her fall apart and start to smell. It becomes even more rotten by that night at the Krusty Krab, so SpongeBob ate her, which made her go, and him sick.
Patty would originally be a tough fish's lunch, but SpongeBob does not want her to get eaten. SpongeBob gives him a Grilled Shoe Burger, and takes Patty to home. Patty then has a makeover and hair-cleaning. Patty goes on an adventure with SpongeBob. SpongeBob sings the song Oh Baby to her as they get attacked by hungry scallops and fall into the end of a waterfall. Patty soon becomes disgusting, smelly, rotten, and is so terrible-looking that people ran away from her. Then, SpongeBob realizes that he must eat Patty, which he does, and due to the repulsive condition of Patty towards her final days, asks Mr. Krabs for a doggie bag.
In To Love a Patty, SpongeBob makes her and falls in love with her. He does a lot of things with her such as going to the beach and singing a song for her. SpongeBob never realizes that Patty had gotten rotten until the end when SpongeBob smelled her.
Relationship with SpongeBob
While SpongeBob was in love with her, She did not really have any feelings for SpongeBob (since she was a Sandwich), SpongeBob was very much in love until it was found out that Patty rotted while SpongeBob was at the Krusty Krab. After Mr Krabs told him about how patties should be eaten, SpongeBob then ate Patty, and asked for a barf bag after doing so.
Relationship with Everyone Else
While SpongeBob fell in love with Patty, everyone else knew that she was just a Krabby Patty.
Patty is seen on the DVD cover of To Love a Patty dancing with SpongeBob. (even though he is holding it)
Another person/thing that is treated like a character that is made of Krabby Patty meat is Krabby Patty Patrick.
Although SpongeBob is asexual, it is unknown why SpongeBob would fall in love with a Krabby Patty.
