Spiny pucs, a type of frog-like being, were classified as amphibians. Both spiny pucs and their larger counterparts, giant spiny pucs, originated from Yavin 4. A different species, known as pug jumpers, were found on Kashyyyk. The name "spiny puc" came from the poisonous, spiny ridges located on its back and sides, which could cause blindness. The skin of spiny pucs was leathery.
Spiny pucs appeared as creatures within the massively multiplayer online roleplaying game Star Wars Galaxies (2003), before the game's service ended on December 15, 2011. The design documentation in From Pencil to Pixel: The Art of Star Wars Galaxies referred to the spiny puc initially as just "frog."
