Yards are creatures resembling small snails with crab-like pincers carrying large, armored shells on their backs. They live in several sections of Maridia in Super Metroid and are seen most of the time moving along the ceilings and walls. A Yard can only be destroyed by Bombs, Power Bombs or the Speed Booster; any other weapon will simply cause them to retreat into their resistant shells. They are harmless while inside their shells, and Samus can even kick or juggle them around by running into them. However, if left alone after kicking them, the Yards will eventually come out of their shells, straighten themselves up, and move directly towards Samus' direction with a drastic increase in speed, attempting to ram her.

Humorously enough, they make odd bouncing noises when kicked.

They also appear in Metroid Fusion, in the seabed-like area of Sector 4. These Yards were captured and brought onboard the BSL Station at an undetermined point before the events of the game, where they were eventually infected and mimicked by X Parasites. The X's ability to manipulate their hosts' DNA has given the Yard-X an increase in size with a radically different shell (now cone-shaped). These variants have also acquired the ability to fire spinning bolts of energy from their shells. However the Yard-X are very slow in their movements, unlike their natural counterparts.

  • The Yard-X from Metroid Fusion bear similar physiology to a Ramulken or Gravitt from SR388.
  • Hacking of Metroid Fusion has revealed unused sprites of the Yard's shell, even though Yards appeared in the game with a different shell. This indicates that the Yard with the original shell from Super Metroid was intended to appear in Fusion, but was dropped.
  • The bolt of energy shot out of a Yard-X's shell is visually similar to Ridley's 2D fireballs.
