Personally I'd starve Toby Fox. It should not take too long given his size. Make him stick thin and so feeble. Then I would feign pity and serve him a plate of delicious char siu meat, with rich, sticky sauce, perfect pancakes, refreshing drinks... go all out. Give that little bastard a banquet. Watch him greedily devour the meat. His lips, teeth, and fingers sticky with the sauce as he throws manners and decorum out of the window in a mad rush to satiate himself. Then, when he's satisfied and feels thing are looking up, I shall reveal he has not been feasting on char siu pork but... char siu Temmie Chang. Yes, I will have ensured Toby Fox greedily gobbled up the flesh of his whore artist that I butchered after growing bored with torturing her. As the tears well up in his eyes and he refuses to believe me, I shall let out a truly evil, bone chilling laugh and upend the contents of a box I'll have near me; it will be the mangled remains of his artist. Her legs gone, her skin flayed, breasts sliced off, eyes missing, her fingers and arms broken, and head twisted around. That is what I would do to that little bastard. The louder he screams and cries in anguish, the louder and more evil my cackle becomes. Hell, it may just kill me because I'll be struggling to breath as I'll be laughing so hard. I will then loop the footage of Temmie Chang being raped by a dog, tortured, and then butchered by me 24/7 at maximum volume. This is the fate that awaits you, you vile little goblin.
