Scurrying Swarmer + Polymorph

[Coinshot Colton]

If a ratfolk had the Scurrying Swarmer feat, and then polymorphs to another small form (say, a halfling), would he still be able to benefit from the Scurrying Swarmer feat?

What if he polymorphs to a medium sized creature?

[Fuzzy-Wuzzy]

Yes, you get the benefit of the feat at any size and shape, since it places no restrictions on those. Deep down you're still a ratfolk, after all. Naturally it does change which allies you can use it with.
