9461-1 - The Swamp Creature

The Swamp Creature was one of the entry-point sets when Monster Fighters launched in 2012, built around a classic swamp showdown. It features a green airboat piloted by hero Frank Rock, sent to reclaim the green Moonstone from the swamp, and the theme's rare Swamp Creature minifigure with molded gill detailing. As one of the smaller, more accessible releases, it's an easy milestone piece for tracking the theme's core storyline.
