This toy octopus concept from Jaehyung Hong is designed to make cleaning up the beach a playful activity for kids. Once all eight orifices are filled with plastic bottles, the octopus will float.
(I presume there are two more slots on the bottom, or the designer just didn’t want to call it a hexopod. Or a sectopod, despite the esteemed history of the term.)
