Glommer has vomit audio in game files, which also persists in it's stategraph file, but the sounds never play during gameplay because the timeline that calls them is overriden by another timeline.
Also, Don't Starve has the same issue.
1. Find or spawn the Glommer. 2. Wait till it vomits some goop (or force it by calling "c_find("glommer").components.periodicspawner:ForceNextSpawn()")
