Sinister Squashlings in Treat Bags

Ok so this is odd, doing the Trick Or Treat quest, Kam got a Hallowed Helm in the treat bag from Razor Hill. Then my druid got a Squashling in another treat bag from Shattrath! Looks like they have been added to the possible drops, so maybe farming treat bags is the way to go. Now if only I could get both on the same character...
