The mustard jelly is a strain of,
or perhaps a relative of,
the ochre jelly.
The monstrous amoeboid mustard jelly,
however,
is far more dangerous.
The only clue to its presence is a faint odor not unlike that of blooming mustard plants.
That and its translucent yellowish-brown color give it its name.

Normally, a mustard jelly attacks by forming a pseudopod of its acidic substance and striking with it.
Those nearby must save vs. poison each round, however,
for the monster exudes a vapor within a 10-foot radius,
and this toxic stuff causes victims to be lethargic and move at half-normal speed unless they save vs. the effect.
Toxic effects last 2 rounds and are cumulative.
This large <L> creature is able to divide itself into 2 smaller,
faster halves (move 12-18").
Each is capable of attacking as well,
but each has only half the hit points <HP> of the whole.
A mustard jelly can,
for example,
flow into a room,
divide into halves which are able to attack independently and simultaneously,
and then form itself into a torus-shape in order to surround a pillar which its prey has climbed.
It cannot move through small spaces, however,
and it cannot move along ceilings as an ochre jelly can.

Although not unintelligent,
mustard jelly is not known to value treasure of any sort.
Of course, it is possible that some treasure might remain after a victim has been devoured.

Mustard jelly is impervious to normal weapons,
and electrical attacks and <&> magic missiles cause it to grow.
The mustard jelly gains hit points <HP> equal in number to the damage rolled.
Cold causes only half damage;
other attack forms are normal.
