The Marble Ong is an Ong and boss character in the game Tick Tock Termination. He is the first Ong battled, appearing in the Ominasia Springs level. His appearance is that of a normal Ong, although he is smaller than most and is white. He is defeated by attacking his head several times. He becomes confused, and he must be lured into the tar pit to be damaged. Once he is hurt three times, he is defeated, and drops the Small Fountain.
