Someone came up with a frog habitat based on Yoda's house in the Dagobah swamp. Why? Who knows! But it is awesome. I suppose the serious Star Wars nerd could build his or her own version of Frogobah out of the model toy Yoda house, which was never intended for the keeping of live frogs.
I actually have one of these “Encounter at Dagobah” kits, but never managed to finish it. Whoever painted the one above (and below) did an amazing job.
Here's the “real” Yoda hut. It looks so cozy, with the round doorway and window holes glowing in the darkness of the swamp.
