Regardless, I would like to donate money to help the Tree Octopus. How can I do this? If you must give money to ease your conscience, donations to help the Tree Octopus should be given directly to the Tree Octopuses. Here is how to donate: Travel to the Olympic Peninsula (if you are a minor, ask your parents first). Stand in the Tree Octopuses' forest near a tree and hold out a dollar bill. If you stand still enough, eventually a Tree Octopus will come by on a branch, reach out, and take the bill with her suckers. She will continue to return for more bills as long as you hold them out, so bring lots of singles. She will use them to line her den in the trees, as the bills will soak up rain water and keep her skin moist. Given the current value of the dollar, this is the most cost effective way to help.
