I'd like to suggest to give Broodmother's spiders their own response rules. They currently do not have sound files for this, but some of Brood's old sound files had spider sounds attached to them. They could be used for this. Giving them their own response rules would allow non-brood heroes to hear them as well (e.g. when sumoned by Rubick, or when dominated). Warlock's Golem has its own, so I don't see a problem with giving some to other non-hero units.

Here are the sounds previously attached to Broodmtoher's responses, separated from her responses. Ideally, half of them would be move responses, and the other half attack responses.
