The purple thing is a Gremlin... and I think the voice belongs to him as well. Again, the palet swaps seem to still be in the game which doesn't make me happy.
And whenever Spector talks about new characters... he just talks about Ortensia, The Gremlins, and the Blotworx... only one of those are new. And seeing how little we saw of the Beetleworx, I'm not sure if that calls for Blotworx yet. I want to see more Beetleworx first.
