Anything that is a Poison-type or a Steel-type (i.e. Magnemite/Magneton) will be immune to Muk's Gas. Everything except Pidgeot is part Poison.

Also, Nidoqueen can indeed learn Roar via TM. Make sure it does not know it already; if it does not, you should find it on the second page of its TM list in-game, in the second column most likely.
