Goblin - No. Turn him in for the plant and get 101-110 mats once per day. Pony - Sort of. After the Tradeskill sig he will collect an item form a node you pass every 90 min. GH Harversters - Devs said at launch it would be later in the Expansion. So perhaps, just not sure when.
They also said that the TS line would upgrade the pony to get PoP mats.. and the dubious ability of it being able to grab 1-13 mats, once every 1.5minutes, if you have it out and it's next to a node is what they gave us.
