Stretch

Stretches are a variant of Boos who are attached to solid platforms. They first appear in Super Mario Bros. 3.

Super Mario Bros. 3
In Super Mario Bros. 3 Stretches are only found in 2 and  3. Stretches can often be found in groups. If Mario or Luigi tries to pass a Stretch, it rises from the top and bottom of its platform and tries to hit him by moving left to right. Stretches can be defeated only with a Starman or hammers thrown by Hammer Mario.

In 1, Stretches themselves do not appear, as the entire castle is devoid of enemies aside from Boom Boom. However, the white platforms that would contain them do appear.

Super Mario Maker series


After a long absence, Stretches reappear in Super Mario Maker, its Nintendo 3DS port (verbally referred to as "Boos"), and Super Mario Maker 2. In the course editor, a Boo will automatically become a Stretch if it is placed on top of or just below a solid block. In this game, they can be placed on any surface, and will pop up more periodically, making them more of an enemy than in their original appearance from Super Mario Bros. 3. Their appearance is slightly different, and they are not connected to a white platform anymore. New sprites for Stretches have been made in all styles. However, they cannot accept Super Mushrooms as attempting to give them a Super Mushroom will turn the Stretch into a Big Boo rather than bigger Stretches, and giving them wings will make them faster and will teleport to the next platform in its direction once it reaches a platform’s edge. Stretches can be defeated in Super Mario Maker like normal Boos, with either a Super Star or a Goomba's Shoe.

In Super Mario Maker 2, Stretches stop moving when looked at in the nighttime ground theme.

Super Mario Run
Stretches reappear in Super Mario Run, where they are usually found in Ghost Houses and act like they did in Super Mario Maker. They have the same appearance as the Stretches in the New Super Mario Bros. U style from Super Mario Maker.

Nintendo Comics System
A single Stretch appears in the Nintendo Comics System short "In the Swim! Fun and Sun Fashions" in an advertisement for swimwear, which depicts it lifting weights on a beach. The Stretch, which has only one face, is shaped like a "Z."
