Can fossils get in igneous rocks

They might but it is far less common than in sedimentary rocks.

Rarely. There is a mold of the body of a rhino killed in a volcanic eruption and then coated in lava. The body rotted away leaving the imprint. It can be seen at the Burke Museum at University of Washington in Seattle, WA. Compare, however, with the hundred/thousands of bones and teeth of rhinos found in sedimentary deposits.

Well, technically speaking, you can get 'mold' type fossils which are in fact just an impression of the original object. The Lava Tree natural park in Hawaii is a great example, and there are also fossilized remains in some tuffs - Pompeii and Herculane for example

There is a famous fossil also in Oregon of a rhinocerus that was covered in lava. Someone figure out what it was.

Note: Looks like Howard just beat me to that answer.
I am reminded of the Pompei archeological dig as well which had many fossilized forms of people as they died in the ash fall.

They can be found in volcanic ash deposits, and sometimes lava flows
there is a lava flow in Oregon that has petrified wood in it, where the trees were preserved in the lava

No , igneous means molten, like lava, the bones would melt or burn before that.
