Sticky Cubes
Sticky Cubes are a very strange type of box. If one Sticky Cube moves into a tile which is horizontally or vertically adjacent to another Sticky Cube, they will both stick to each other and won't be able to be moved. If Sticky Cubes are horizontally or vertically adjacent to each other at the beginning of the level they will not stick. Stuck sticky cubes cannot be destroyed unless a Powder Keg is exploded next to one then the stuck sticky cube will appear to have smashed but the tile which the stuck sticky cube was on will still remain unable to be walked upon as if it were still there. These boxes only appear in the Platinum Edition of Return To Wonderland.
