I would like to tell you about my favourite cartoon hero - Sponge Bob Square Pants. He is the main character of the cartoon, which was called in his honour. Sponge Bob lives on the bottom of the ocean in the pineapple, that serves him as a house. He lives there with his pet - Gary the snail. Sponge Bob is a yellow square shaped marine creature. He wears brown square pants, white socks with red and blue strips, white shirt, red tie and black boots. Sponge Bob is very hard-working, reliable, responsible and conscious. He works as a cook in the eatery "The Krusty Krab". Sponge Bob is very friendly, His best friend's name is Patric. Besides Patric among Sponge Bob's friends are Squidward, Eugene Krabs, Sandy, Perl and many others. Sponge Bob is mad about jelly fishing and cooking. Also he likes to blow bubbles and to play with his friends. I consider Sponge Bob to be one of the most famous and cute cartoon characters in the world.
