Vitreous surprisingly makes in appearance in Riolu947 64: The Lost Legend. As a bellyache creator, he can invade anyone's stomach and cause mental pain! Vitreous is also the one who invaded my belly when I got that bellyache!
If he's in the mood, he'll use his green jellylike fluid to make someone's belly expand!
There are three ways to defeat Vitreous:
- Go into someone's stomach and fight him
- Drink a fluid called the Stomach Relief
- Rub someone's belly for at least three minutes
