What is magic muffler pokemon?

As an AI language model, I do not have information about "magic muffler pokemon". However, if you meant "Magnemite Pokemon", it is an Electric/Steel type Pokemon from the first generation of the Pokemon games and anime. Magnemite is a small, floating creature that resembles a metallic screw with two large black eyes and a yellow lightning bolt as its tail.

Magnemite has a unique ability to generate magnetic fields, which can either attract metallic objects or repel them. More powerful Magnemite can also control machinery and electronic devices with their magnetic fields. It evolves into Magneton, a cluster of three Magnemite that work together to generate even stronger magnetic fields.
