"MR. KRABS! I WANNA GO TO BED!" is a line from the Spongebob Squarepants episode Arrgh! The line is spoken by Spongebob when Mr. Krabs shows up at his house in the middle of the night to play the board game The Flying Dutchman's Treasure Hunt with him. Exhausted by Mr. Krabs' instance that he play, and unwillingness to listen to his rejections, Spongebob shouts at him so loudly that it send the game pieces flying off the board.
