Well, do they have confirmation that the bait was actually taken... or is the dragon setting up a trap of his own...

Dragon: "Oh, this talking toffee goat is soooo good... I can't believe they are actully stupid enough to think I'll fall for this, so hard to find good adventurers these days... So good. Mmm, it tastes like a little slice of heaven... They do realize that I breathe fire, right? I mean, they expect toffee to withstand jets of flame exhaled from a dragon? I sure hope the villagers bring me more of these magical talking candy goats... I'm going to burn the village down on principle."
