a sorry tale she said and then she wagged and flipped away.
To keep to this place sniffing up all this dust would be too much enjoyment for one pussy cat.

Amphioctopus marginatus, also known as the coconut octopus and veined octopus, is a medium-sized cephalopod belonging to the genus Amphioctopus. It is found in tropical waters of the western Pacific Ocean. It commonly preys upon shrimp, crabs, and clams, and it has a number of unusual behaviors, including bipedal walking and gathering of coconut husks.

Although octopuses often use foreign objects as shelter, the sophisticated behavior of A. marginatus when they select materials, carry and reassemble them, is far more complex.[4] The researchers define a tool as "an object carried or maintained for future use", and, according to that definition, the behavior of A. marginatus is the first documented case of tool use in invertebrates.[4][6] While the hermit crab reuses a shell which it maintains,[7] what makes A. marginatus different from the hermit crab is that A. marginatus collects shells for future use, so when the octopus is transporting the shell, it is not getting any protection from the shell, which is considered highly unusual by the researchers.[4]
