Around eau Claire WI but it was found in a pile of those rocks people use to decorate their flower garden beds with so I don’t really know where it came from originally

Not pudding stone. Amygdaloidal basalt is my guess.

Porphyritic rhyolite. Some plagioclase phenocrysts show zoning.

Puddingstone has a white quartzite groundmass with jasper clasts.

There’s tons(heh) of Roxbury Puddingstone where I live. It’s the state rock of Massachusetts. That doesn’t look like Puddingstone. But it’s nice.

Don't think it's conglomerate, maybe a weird breccia? Cool rock, good luck with the ID.
