My favourite cartoon character is SpongeBob SquarePants. It is an American cartoon with many series. SpongeBob lives in underwater city Bikini Bottom.
He has got many friends. He is an energetic, optimistic, cute and yellow sea sponge. His house looks like a pineapple. He works as a cook at the Krusty Krab . SpongeBob has got a pet. It is a snail. Its name is Gary. This cartoon is very funny and entertaining.
There are also other unforgettable characters in this cartoon. At first sight this cartoon seems unserious and the main character itself is naive, silly and stupid . But all these characters are the personification of the seven deadly sins. The authors of this cartoon mock at such traits of character which people have .Here is the list of them :
SpongeBob - Lust
Mr. Krabs - Greed
Patrick Star - Sloth
Squidward -Wrath
Sandy Cheeks - Pride
Gary - Gluttony
Sheldon Plankton- Envy
