The Plunger

From TheKolWiki

Welcome, Citizen. I am known as The Plunger. If you've got anything you need pasted together, I'm your Gnoll. I've learned to use the vacuum created by my plunger as a substitute for Meat Paste. It doesn't cost a thing!

He can combine your items for free without the use of meat paste.

The Plunger is located in Inside Degrassi Knoll, which can only be accessed after ascending under a Muscle Zodiac sign.

The Plunger takes your items, fuses them together by mashing them with his plunger, and hands you the result.

Those items don't combine to make anything, Citizen. Perhaps we should try something else.
