Ooze Cube
The table takes up its entire space. Other creatures can enter the space, but a creature that does so is subjected to the table's Engulf and has disadvantage on the saving throw.
Creatures inside the table can be seen but have total cover.
A creature within 5 feet of the cube can take an action to pull a creature or object out of the table. Doing so requires a successful DC 12 Strength check, and the creature making the attempt takes 10 (3d6) acid damage.
The table can hold only one Large creature or up to four Medium or smaller creatures inside it at a time.
One Body
The gelatinous table is part of the House Mimic that controls it. Therefore, the house mimic take the full HP of this construct in damage at the beginning of its next turn after this construct is destroyed.

Engulf
The table moves up to its speed. While doing so, it can enter Large or smaller creatures' spaces. Whenever the table enters a creature's space, the creature must make a DC 12 Dexterity saving throw.
On a successful save, the creature can choose to be pushed 5 feet back or to the side of the table. A creature that chooses not to be pushed suffers the consequences of a failed saving throw.
On a failed save, the table enters the creature's space, and the creature takes 10 (3d6) acid damage and is engulfed. The engulfed creature can't breathe, is restrained, and takes 21, 6d6, acid damage at the start of each of the table's turns. When the table moves, the engulfed creature moves with it. An engulfed creature can try to escape by taking an action to make a DC 12 Strength check. On a success, the creature escapes and enters a space of its choice within 5 feet of the table.
