On this fun-filled coloring page, a cheerful yellow sponge with a distinct square body and big blue eyes is standing with a wide smile. He is wearing a pair of bright red shorts with white polka dots, and his thin arms and legs are topped with large hands and feet. To color this unique picture, use bright yellow for the sponge's body and a light blue for his eyes. Select a cheerful red for the shorts, and bring the picture to life by adding white polka dots. Give the sponge a highlight of light pink for his cheeks and a rosy red shade for his mouth. Choose a light brown for the arms, legs and feet to keep the focus on the Sponge's quirky personality.
