The Wall Jump Block is a black plate placed vertically on a wall. Its edges are outlined in red and its sides have a pattern of orange arrows pointing away from the wall.
Wall Jump Blocks appear usually only in the side-scrolling sections of Act 2 of each stage, where they indicate the places where Sonic the Hedgehog is able to Wall Jump. Wall Jump Blocks are also utilized in the Perfect Chaos boss fight. This is also seen in one point of Egg Dragoon boss fight, where Eggman materializes two large walls from the machine to squash Sonic, During that time, the player has to do Wall Jump before Eggman pushes the wall plates together to crush Sonic.
- The only time Sonic is able to Wall Jump without a wall jump block is a shortcut in the temple area section of Seaside Hill Act 2.
- This is the second time in a game that Sonic has been able to perform a certain action only in a certain area. (In Sonic Colors, Sonic can Quick Step and Drift only in specified areas)
