Item description:
Poison
- Interactable Item that drains a player's health to zero
Fish food
- Intractable item that provides 50 percent of the maximum health back, caps at maximum health
Pellets
- Intractable item that provides 25 percent of the maximum health back, caps at maximum health

All pngs were created by me and are meant to just be sample fill ins.
