It's some sort of frog, according to Wikipedia:
Nasikabatrachus sahyadrensis is a frog species belonging to the family Sooglossidae. It can be found in the Western Ghats in India. Common names for this species are Purple Frog or Pignose Frog. It was discovered in October 2003 and was found to be unique for the geographic region.That is the weirdest frog I've ever seen. It is not an attractive beast, that's for sure! It looks like badly set milk pudding.
Nasikabatrachus sahyadrensis has the appearance of a typical frog. It has a squat body, somewhat rounded compared to other more dorsoventrally-flattened frogs. Its arms and legs splay out in the standard anuran body form. Compared to other frogs, N. sahyadrensis has a small head and a rather peculiar, pointed snout. Adults are usually dark purple in color. The specimen with which the species was originally described was seven centimeters long from the tip of the snout to the tip of the urostyle. Also, its cry sounds more like one from a chicken.
