The number of Tonberries the player needs to defeat to engage the Tonberry King changes with the beginning of each new file, however, it is usually about eighteen to twenty-four. Should the player run from the Tonberry King, they will have to fight the prerequisite number of Tonberry enemies again to make him reappear. If the player successfully cards a Tonberry, it does not count as defeating it.
The player may leave the area and save the game while in the process of killing the required number of Tonberries. Killing them consecutively is not required.
"It's Sharp!" is a single target attack using the equation of a target's enemy kills multiplied by 30. "Junk" is a counterattack made after every fifth attack the party deals against Tonberry King that sends items falling down on the party for a random amount of damage. The items are pot, a kettle, a bottle of wine, cups, soccer ball, and even a television. On top of these, Tonberry King uses a regular physical attack.
One might want to wait till the party's average level is beyond 30 before engaging Tonberry King, as he is one of the rare enemies in the game that has Full-life in his Draw list.
