The Fantasy Castle is a members-only land den that was released during 2012. It was formerly sold at the Den Shop until it was removed sometime during 2017.
The Fantasy Castle is a fancy castle overhanging a cliff and includes four rooms, two outdoor spaces, and a waterfall. Jammers can swim through part of the waterfall next to a small bridge. The background of the den reveals a small river running along rolling hills that lead to sharp mountain peaks with a rainbow and puffy clouds in the sky.
