One of the toughest enemies around, its Bad Breath/Sour Mouth attack causes every status problem there is. It looks like a giant round plant with tiny waving tentacles around a large black mouth. The "Oscar" translations from FF6 may be references to Sesame Street's Oscar the Grouch, whom the Malboro acutely resembles.
CP: Being a hideous creature with greenish-brown mottled skin, and writhing tentacles. It eats only of flesh, drawing no sustenance from photosynthesis as do common plants. Favoring stealth, it approaches its prey in silence, then strikes without warning, swallowing its victim whole. Its maw is filled with powerfully acidic saliva, and breathing the miasma that is its foul breath causes poisoning and madness.
