The blue crate has the same dimensions as the regular Wooden Container. However, it is instead made of metal, has a blue coloration, and is emblazoned with a white star surrounded by a blue and red circle.
Blue crates can be found everywhere in the game, although they are the rarest form of Container. When destroying a blue crate in gameplay, it releases a blinding light that paralyzes all enemies in the vicinity for a short of time, as if they have been hit by Psycho Smash or Psycho Shock. However, the blue crates cannot paralyze enemies that have their guard up, like Golems or Egg Guardians. In rare cases, the blue crates can even destroy enemies.
