Eldorian reports that it has been confirmed by Blizzard that the Hallow’s End pet and helm are now random in the trick or treat bags - they don’t only drop from the Headless Horseman now. I don’t usually do seasonal quests except the Brewfest, but I decided to do all the Hallow’s End quests. Thus far I have done all of Kalimdor and Eastern Kingdoms achievements. I will do the Headless Horseman as soon as I reach Tirisfal Glades. The quest says he is in Scarlet Monastery.

Just got a Sinister Squashling from the Crudely Wrapped Gift you get from the daily "Smash the Pumpkin" after you put out the fires. I guess it can drop from those too.
