Some of the known Cut Content:

Splitting:

The ability to split yourself into a smaller Monster, allowing you to switch inbetween both Monsters for solving puzzles or perhaps even distraction. (The actual splitting mechanic doesn't appear to be in the original Demo/Sneak Peek though the ability to switch between monsters is apparent (Used in some Custom Levels). The ability to switch monsters doesn't work in the Beta version of the Sneak Peak however.)
