Consume Corpse

The wiggly cube covers and consumes the flesh
on a corpse over the corpse of a minute.
While doing so, the cube's armor class is reduced
by 4, and it connot move, act, or react while
consuming the corpse, except to abandon the
corpse.
Upon completion, the cube's base size increases
to the size of the consumed creature, for an hour,
up to a maximum to Large.
