Description
Movable Crate has the same dimensions of the regular steel containers, however instead of being destroyed by the character, it is used for either destroying multiple enemies with single attack or to block the way of the character. To use it in gameplay, the player has to use a special attack used only for this purpose which is a variant of the Boost named as Kick to push it with great force that knocks anything caught in the Container way.

Sonic Colors
In Sonic Colors, it appeared in both 3D and 2D sections with a silver color and black frames, they can be pushed either by just moving at them or by using the Kick move.

Sonic Generations
In Sonic Generations, it has different schemes between levels, from an electronic yellow-steel container to a silver steel container. Like Sonic Colors, the player can move them by moving the control stick at them or kicking them as a more faster way.
