My bad, I just reread your post. The ambient part or the low-fi part of the intro of a Match Made in Heaven?
Josh has said in interviews he uses a Strymon Big Sky with the Cloud mode/setting. Maybe try the sky type reverbs in the Fractal (cirrocumulus, cumulonimbus, nimbostratus & stratocumulous) for the ambient part. The lo-fi is just a filter, eq or extreme low cut. Someone else may be able to help with Animals. Watching live videos, it's not played on guitar.
