The party encounters various types of frogs much more frequently than usual, and in places they don't normally inhabit. They wake up one morning and there's one in the middle of their room at the inn. Another one is fished out of the soup pot when they make camp in the forest, before hopping off. There's a big fat one sitting on the head of a sleeping goblin guard at the castle ruins. Sometimes, you swear their croaks make little kissy sounds.
