Puddle is Crest's "helper" which normally takes care of the spiders, (or she helps Crest more often). She will reward you an "Inflatable Dolphin" when you saved Crest from killing the spider "black speck". The Inflatable Dolphin Is used for scaling the rock in order to go to the park. If you take pictures of Crest, you have to fight Puddle. Alternatively, you can not take any photos and Crest will think you were following her since you were to shy to ask for doggy treats, and she give you them because she's so nice.
