Please help us save the rare Pacific Northwest Tree Octopus by signing up for the "Trick or Treat for Tree Octopus" program. Like Unicef, you can build your own collection box and go door to door on Halloween, or any day, asking your neighbors for candy corn or shrimp.
When you have filled the box with treats, hang it on a branch in a forest where tree octopuses dwell. The tree octopus enjoys the challenge of removing these treats from the box.
