Junk is a type of edible(and harmful) object that appear in Hungry Shark World.
There are multiple different types of junk bits including plastic bags, bottles and multiple items that were thrown into the water. All garbage is surrounded by a small greenish cloud of pollution, making them quite easily noticeable.
How it functions
Junk is edible, but it's highly required to avoid eating it unless you need to eat it for a mission. Every time a shark eats junk it instantly looses a small bit of health and the health drain is increased for a split second, giving the accolade "Yuck!" It appears in every single ocean in the game and is really common, especially in the Arabian Sea which makes it easy to accidentally lose health by eating the garbage.When you are in a Gold Rush,eating Garbage gives you coins and does not harm you, so try to eat as much of it as you can, to clear the area for easier movement.
