This automaton looks like a humanoid-shaped semi-transparent amoeba. Small indentions appear to serve as the creature’s eyes. No other facial features are present.

A gelatinous golem’s acid does not harm metal or stone.
A gelatinous golem can try to wrap an opponent up to one size smaller than itself in its body as a standard action. The gelatinous golem attempts a grapple that does not provoke an attack of opportunity. If it wins the grapple the gelatinous golem establishes a hold. Attacks that hit an engulfing gelatinous golem deal half their damage to the golem and half to the engulfed victim.
An engulfed opponent is subjected to the gelatinous golem’s paralysis and acid each round it remains trapped. A trapped opponent can do nothing other than attempt to escape. Further, an engulfed foe must hold its breath or begin drowning (see the Core Rulebook for the drowning rules).
While engulfing an opponent, a gelatinous golem is not considered grappled and can move and attack normally.
A gelatinous golem is hard to see, even under ideal conditions, and it takes a DC 15 Perception check to notice one. Creatures who fail to notice a gelatinous golem and walk into it are automatically grappled (if the golem chooses to grapple the opponent).
