Slimes play player footstep sounds underneath their squishy sounds

When slimes roam around or advance towards their enemy, you can hear a player foostep sound underneath their normal squish sounds. This is most obvious for baby slimes because their squish sounds are currently broken and don't play, so you only hear the foostep sound.

The expected behavior is that slimes only play the squish sounds. Playing two different sounds for the same event is anomalous.
