Goofy character. By his seventh appearance, in Orphan's Benefit first released on August 11, 1934, he gained the new name "Goofy" and became a regular member of the gang along with two other new characters: Donald Duck and Clara Cluck. Trio years with Mickey and Donald Mickey's Service Station directed by Ben Sharpsteen, first released on March 16, 1935, was the first of the classic "Mickey, Donald, and Goofy" comedy shorts. Those films had the trio trying to cooperate in performing a certain assignment given to them. Early on they became separated from each other. Then the short's focus started alternating between each of them facing the problems at hand, each in their own way and distinct style of comedy. The end of the short would reunite the three to share the fruits of their efforts, failure more often than success. Clock Cleaners, first released on October 15, 1937, and Lonesome Ghosts, first released on December 24, 1937, are usually considered the highlights of this series and animated classics. Progressively during the series, Mickey's part diminished in favor of Donald, Goofy, and Pluto.

They have settled in the Arctic for an unspecified period of time, to capture live walruses to bring back to civilization. Their food supplies consist of canned beans. The focus shifts between Goofy trying to set traps for walruses and Donald trying to catch penguins to use as food — both with the same lack of success. Mickey would return in The Whalers, first released on August 19, 1938, but this and also Tugboat Mickey, released on April 26, 1940, would be the last two shorts to feature all three characters as a team. Solo series Goofy next starred at his first solo cartoon Goofy and Wilbur directed by Dick Huemer, first released on March 17, 1939. The short featured
