Players simply need to lure the Bunger's close to one another and then cover each Bunger in Ketchup. Covering each Bunger in Ketchup makes both Bunger's run into each other, stunning them. With each Bunger stunned, players simply need to walk about to one and catch it in the net.
How do you get Bunger by itself?
Get him as close as possible throwing ketchup on the floor. Once they're close enough, throw a ketchup on one of them, and the other will run into it and stun it. When the creature is stunned, you can catch it, i.e. obtain it.
How do you catch a Bunger bug snack?
Bunger can be caught using the Bug Net. To catch Bunger you need to have it run into another Bunger. This can be done by covering one Bunger with either ketchup or mustard using your Sauce Slinger and luring the other Bunger over to it. The Bunger will charge towards the other Bunger, knocking it over and stunning it.
