The teacher, Mr. Slink, assigns an environmental project, and Halo
Nightly pairs up with Flora, the school's resident treehugger. Their
team has the assignment in the bag (reusable, of course). But when the
evil Doozie Hiss ruins their chances for a good grade, Flora changes
from happy hippie to eco-terror. With her superpowered candies, Halo
faces off against the Green Queen of Mean!
