Moving Crate

Moving Crate is a gimmick that appeared in Sonic Unleashed and Sonic Colors. It simply an electronic container which is used by Doctor Eggman to defeat Sonic.

Description
Moving Crate is unlike all the other Containers, as it is electronic gifted with artificial intelligence to exile anyone it sees. Moving Crate is blue and has a special sensor which is very sensitive as when the character moves in front of it, then it will changes to red and extends and push the player from the gameplay which makes him lose a life instantly without losing rings first. They are also one of the rarest objects that can hurt Super Sonic.

Sonic Unleashed
In Sonic Unleashed, it appeared only in Eggmanland which is used to push the character from the gameplay arena making him lose a life. In this game, it has a moving Eggman's face on it's center which will smiles when it sensed an enemy in front of it. It serves as one of the most difficult objects to evade in the level.

Sonic Colors
In Sonic Colors, it has the same attributes that it has in Sonic Unleashed, however Eggman's face has been removed from it. Like the Previous game, it has a sensor which will turns the crate to red and extends the crate itself to push the enemy. It appeared in Asteroid Coaster and Starlight Carnival stages.
