The landing gear are normally retracted immediately after take off upon establishing a positive rate of climb. There are occasions when the landing gear are left extended for a short period of time such as when the brakes are hot or overheated. Normal call outs after rotation when the non-flying pilot confirms that the aircraft is climbing are, "Positive rate--gear up." The landing gear are retracted as soon as possible after take-off so as to reduce drag on the aircraft, which allows it to gain airspeed and climb quicker.
"wheels up" is when an airplane is off the ground. When someone says they are going "wheels up" it means they are flying soon.
No, an airplane does not have legs but the wheels and everything that holds up the rest of the plane is called the gear or landing gear.

They rotate and can be braked, just like auto wheels. Nose wheels can be steered.
If the airplane has "retractable" landing gear, the wheels and struts fold up inside the wings, or belly, or engine compartment of the plane. Sometimes openings where the wheels go (wheel wells) are covered with doors when the gear is retracted, but sometimes the gear itself has a cover on one side and that's the side that forms the flat surface on the bottom of the airplane when the gear is retracted. Some small aircraft have "fixed landing gear." Those wheels don't go anywhere. They just hang in the air as the plane flies. These airplanes rarely go over 180 miles per hour, so the gear is not damaged by the wind. With bigger and faster aircraft the gear must be retractable so it is not damaged.

An Airplane. Me. My sister when she is mad.
This is because when the plane comes down, it's gentle and slow. Think of a toy airplane. If it has wheels and slowly comes down, it won't bust if it doesn't go roughly, right (I hope)?
Aircraft can go up to about 1,600 mph .
the elevators on an airplane is used to change the airplane's pitch. The pitch of an airplane is what makes the airplane go up and down without turning, if you turn, that would become roll.
