Magic Moss

Magic Moss is a magical plant that appears in the episode "Lars and the Cool Kids."

"Lars and the Cool Kids"
The moss was originally cared for by Rose Quartz and grows in a lagoon known as Dead Man's Mouth. The moss attacks Buck, Jenny, and Sour Cream by wrapping around them until covering their bodies. Steven and Lars manage to transport the moss up the hill, where Rose used to take it. The moss covers everyone completely, but it then bloomed into thousands of pink gemmed flowers freeing Steven and the others. Everyone watches the flowers drift above Beach City, and Steven draws the conclusion that the moss only wanted to bloom.

Trivia

 * Though this moss blooms into flowers, regular moss does not.
 * The centers of the flowers are similar to rose quartz gems.
