Jumble Grass

Boober collects Jumble Grass from the Cave of Shadows

The Cave of Shadows is an eerie cave where shadows move around the cave's walls. Boober must summon all his courage to go there. It is also the only known location to harvest the ingredients for Boober's Doogan Berry Tea - comprised of doogan berries, jumble grass (anti-viral) and moonrose (fever reducer). It is seen in the Fraggle Rock episode "Pebble Pox Blues".
